LaserDisc

• 1. Introduction

  ›

  LaserDisc arrived in American living rooms on the 11th of December 1978, under a name almost nobody remembers: MCA DiscoVision. The first title available was Jaws, pressed onto a shiny silver platter twelve inches across, read by a beam of light rather than a needle or a magnetic head. It was something genuinely new in the world. Here was a home video format that could freeze a single frame with perfect clarity, jump to any chapter in seconds, and deliver audio so clean it matched what listeners were getting from compact discs. And yet, by the time Pioneer shut down the last production line in July 2009, fewer than one in fifty American households had ever owned a player. How does a format that was technically superior to its rivals in nearly every measurable way end up a footnote? And why do collectors in the United States and Japan still seek these discs out today, more than two decades after the format's commercial peak?

• 2. Origins in Light

  ›

  David Paul Gregg and James Russell began working on a transparent disc-based optical recording system in 1963, and their concept was patented in 1970. MCA bought the rights to that technology in 1968. Philips, working independently, had developed a reflective videodisc by 1969, a method with practical advantages over the transparent approach. The two companies began collaborating in the early 1970s and gave their joint creation a series of working names: Optical Videodisc System, Reflective Optical Videodisc, Laser Optical Videodisc. Philips preferred to call it VLP, after the Dutch phrase Video Langspeel-Plaat. The format had no official name at all until 1980, when the LaserVision Association, made up of MCA, Universal-Pioneer, IBM, and Philips/Magnavox, settled on "LaserVision" as the standard designation. The commercial launch that preceded this naming decision happened in Atlanta, Georgia, two years after VHS debuted and four years before the compact disc reached consumers. Philips built the players; MCA pressed the discs. That partnership proved unsuccessful and was dissolved after several years, opening the door for Pioneer to take the lead.

• 3. How the Disc Worked

  ›

  A standard LaserDisc measured 300 mm across, close to the diameter of a 12-inch phonograph record, and weighed about 250 grams. Unlike a vinyl record's groove or a magnetic tape's coating, the information on a LaserDisc lived in a pattern of microscopic pits and flat areas called lands, pressed into the disc surface. A laser read those patterns during playback, reconstructing the original signal without ever physically touching the data layer. The video signal itself was analog, not digital: a carrier frequency was modulated by the picture information, giving the format roughly 425 to 440 horizontal lines of resolution for NTSC and PAL respectively. That was nearly double the 240 lines available on VHS. Audio came in two distinct forms. Early releases carried analog stereo, encoded using frequency modulation. Later discs added digital stereo at the same 16-bit, 44.1 kilohertz specification used on compact discs. By the 1990s, some titles carried Dolby Digital and DTS surround sound, making LaserDisc the first home video format to support surround. Dolby Digital on LaserDisc was handled differently than on DVD: the signal was stored in a frequency-modulated form within the analog audio track, and extracting it required a player with a special AC-3 RF output plus an external demodulator to convert the 2.88 MHz modulated signal into the 384 kilobit-per-second stream that a decoder could handle.

• 4. CAV, CLV, and the Rotation Problem

  ›

  Because digital compression was not yet practical in the late 1970s, engineers had to find other ways to fit a feature film onto a disc. They settled on two main playback modes, each with its own trade-offs. CAV, or constant angular velocity, spun the disc at a fixed 1,800 rpm for NTSC and stored exactly one video frame per revolution, yielding 54,000 individually addressable frames per side. That meant a viewer could enter a frame number on the remote and jump directly to it. Film scholars valued this capability for studying staging and continuity. The limit was time: 30 minutes per side for NTSC. CLV, or constant linear velocity, traded those advanced features for duration, slowing the disc's rotation gradually from 1,800 down to 600 rpm and stretching capacity to 60 minutes per side for NTSC. Most LaserDisc titles used CLV. High-end players with a digital frame store could simulate freeze-frame and variable-speed playback on CLV discs, but base-level CLV players could not. A third mode, constant angular acceleration or CAA, was introduced in the early 1980s to address crosstalk distortion that plagued CLV; it changed rotation speed in controlled steps rather than continuously. Most disc manufacturers quietly adopted CAA, though the term rarely appeared on consumer packaging. When digital audio was integrated in 1985, CAA discs initially lost five minutes of capacity per side, dropping to 55 minutes. Pioneer resolved that by 1987, restoring the full 60-minute ceiling and eventually pushing select titles to 65 minutes per side.

• 5. Pioneer's Dominance

  ›

  In 1980, Pioneer acquired a majority stake in the format and began reshaping it in its own image. Pioneer's consumer players debuted in Japan in October 1981, and the company eventually sold 9.5 million of the 16.8 million LaserDisc players manufactured worldwide. The LD-700, released in March 1984, was the first consumer player to use a solid-state semiconductor laser rather than a gas helium-neon tube, and the first to load from the front rather than the top. Before Pioneer's move, Hitachi had introduced an industrial laser-diode player, but it suffered from a poor dropout compensator and was produced in small quantities only. After the LD-700 arrived, gas lasers disappeared from consumer units. Pioneer also pushed into specialty applications: the Pioneer DVL-9, introduced in 1996, was both the company's first consumer DVD player and the first combination DVD and LaserDisc player. At the high end, Pioneer's HLD-X0 became the world's first high-definition video player, using NHK's MUSE analog HDTV system. Even its mascot had personality: on single-sided discs mastered by Pioneer, inserting the wrong side produced a still image of a cheerful upside-down turtle with a LaserDisc for a belly, captioned "Program material is recorded on the other side of this disc." Pioneer remained the last manufacturer standing; the company ended player production in July 2009 and continued offering maintenance services until the 30th of September 2020, when its remaining parts inventory was exhausted.

• 6. Special Editions and the Criterion Standard

  ›

  LaserDisc's capacity for multiple audio tracks created a category of home video release that had not existed before. The 1984 Criterion Collection edition of Citizen Kane is generally credited as the first "Special Edition" release in home video history, and King Kong holds the distinction of being the first release to include an audio commentary track. These discs bundled interviews, commentary, documentaries, and still photographs in a way that VHS could not match. The format also preserved films in ways no subsequent release has replicated. The 1995 THX LaserDisc box set of Jaws was the first time the film's original soundtrack was available on home video; a time-compressed CLV re-issue had replaced incidental background music due to licensing costs. One Universal and Columbia co-production, The Electric Horseman, has never been issued in any other home video format with its original score intact, and the 1989 and 1996 LaserDisc releases of E.T. the Extra-Terrestrial remain the only formats to include a cut scene of Harrison Ford as a school principal. Disney's Song of the South, unavailable in the United States in any format, was issued in Japan on LaserDisc. These gaps between what LaserDisc preserved and what DVD later offered explain why certain titles remain sought after by collectors more than two decades after the format's peak.

  The format's random-access capability attracted users well outside the home video market. In 1986, a SCSI-equipped LaserDisc player attached to a BBC Master computer anchored the BBC Domesday Project, storing video, audio, and binary data encoded within CAV frames. Each side of a Domesday disc could hold up to 324 megabytes of data when all 54,000 frames were devoted to binary storage. In the mid-1980s, Lucasfilm built the EditDroid, a non-linear film editing system driven by computer-controlled LaserDisc players. Only 24 EditDroid systems were ever built, but the concepts they introduced remained in use long after. The first mass-produced industrial player, the MCA DiscoVision PR-7820, found a home in General Motors dealerships across North America in the late 1970s and early 1980s, where it presented training videos and new vehicle showcases. Video arcades found an entirely different use for the format's instant-access capability: Dragon's Lair and Space Ace, produced by Cinematronics and American Laser Games, were interactive movie games running off LaserDisc media, beginning in 1983 with Sega's Astron Belt. Under contract from the United States military, Matrox built a combination computer and LaserDisc player for instructional purposes that together weighed 43 pounds, with handles provided in case two people were needed to lift it.

• 8. Decline and What Remained

  ›

  By 1995, several companies were already investing in DVD, and by 1996 awareness of the new format had begun to noticeably reduce LaserDisc player sales. The last LaserDisc title released in North America was Paramount's Bringing Out the Dead, on the 3rd of October 2000. Japan kept the format alive longer: new titles continued until the 21st of September 2001, the final film being Tokyo Raiders, a Hong Kong action movie from Golden Harvest. The last known LaserDisc release of any kind was a karaoke title, Onta Station vol. 1018, issued exclusively in Japan on the 21st of March 2007. Market penetration in Japan had reached roughly 10% of households by 1999; in the United States, about 2% of households, or approximately two million, owned a player at peak. Laser rot complicated the legacy of many early discs: adhesive impurities penetrated the lacquer seal and attacked the aluminum reflective layer, producing anything from black spots resembling mold to degradation invisible to the naked eye. As of 2021, a small but active collector community persists in both the United States and Japan, drawn partly by the films that never made it to DVD and partly by the analog image quality that some videophiles still prefer for certain titles.
