quality due to an inadequate drop-out compensator, was made only in limited quantities. After
Pioneer released the LD-700, gas lasers were no longer used in consumer players, despite their advantages, although Philips continued to use gas lasers in their industrial units until 1985. Helium-Neon gas lasers had a shorter-wavelength laser that created a much smaller spot on the disc, leading to better tracking of imperfectly manufactured discs, such as an off-center hole punch or slightly eccentric tracks. The use of a solid state laser diode necessitated the introduction of the tilt-servo mechanism in LD players; this physically tilted the entire laser table, keeping it parallel with the disc, thus ensuring the larger laser beam spot was always perfectly circular and helping to reduce or eliminate crosstalk on warped CLV discs. In addition, the gas laser was less sensitive to external vibration, a must in certain industrial environments, and generated less photon-shot noise than the solid-state laser diode, resulting in a cleaner, less "busy" on-screen image.

identical to the Elite LD-S1. The LD-W1 remained in the
Pioneer catalog for many years and received many improvements: While the first version of the W1 had only 2X oversampling and 16-bit D/A converters in the digital audio, the later units had 4X oversampling with 20-bit D/A converters. The video noise reduction was improved, too, sharpening the picture and reducing disc noise while eliminating the artifacts it caused. In addition, high-frequency response in the FM video demodulator and A/D-D/A converters was extended and flattened, increasing resolution and reducing visible digital artifacts. The W1's player software was refined too, making disc and side-changing faster, plus, during side or disc changes, it grabbed a still-frame closer to the actual end-of-program instead of just any frame from the side's last five minutes.

the direction of the disc's rotation, simultaneously moving the laser pickup head to the other side of the disc, and then initiate playback. Since LDs are made up of two single sided discs glued together, the auto-reverse player would center each disc side individually. LaserDisc players used either a simple U-shaped reversing mechanism, known as "Epsilon Turn", or technique known as "Gamma Turn", where the player physically rotated the laser reading head 180° as it moved from one side of the disc to the other, ensuring that the laser retained the same playback orientation on both sides of the disc. Some players even had twin laser reading circuits to eliminate excessive servos.

trapped under the surface of the disc (inclusions), an off-center hole or track errors created during mastering, such as track-to-track "kissing" (tracks touching). Because of this, collectors with large MCA DiscoVision collections (DiscoVision discs had just those type of above mentioned defects) tended to use tube-based LaserDisc players, since they played these discs better. In addition to being the first LaserDisc player to use a laser diode, the
Pioneer LD-700 was also the first player ever to have the aforementioned "tilt" servo, which was arguably one of the greatest advances in LaserDisc players, providing superior tracking.
298:
the disc radially to provide tracking instead of moving the laser radially. MCA engineers designed the player at the DiscoVision labs in
Torrance, California and Universal-Pioneer mass-produced it in Japan. The 7820 was such a high quality player that MCA themselves used it at their DiscoVision disc pressing plant in Carson, California for quality control checks of both master discs and finished sets. Unfortunately, this caused problems because the 7820 could easily play discs that the poorly designed and quite primitive consumer player, the Magnavox VH-8000, simply could not cope with.

modern standards, and does not support progressive scan (480p) even though it has component output. As noted above, the LD section, while competent, is inferior to earlier high-end LD players. A few
Pioneer dealers offered North American specification DVL-919s, and a unit purchased in April 2004 had a manufacture date of December 2003. Manufacturing of the DVL-919 continued until January 1, 2009, when Pioneer announced that production would cease after a final production run of 3000 DVL-919 and other model laser disc players.

The Pioneer Elite DVL-90, an updated version, followed by a similar, though supposedly lower-end model, the DVL-700, were released in 1997. Successors to this model include the Pioneer DVL-909, Pioneer DVL-919, and the Pioneer Elite DVL-91. Although the DVD/LD combi players offered competent LD performance, they paled in comparison to high-end LD players such as the Pioneer Elite CLD-99 and the Pioneer Hi-Vision/MUSE HLD-X9.

The comb filter present in these players is unique and is purportedly the finest comb filter ever used in consumer A/V gear: it is still in use in Mitsubishi's top-spec CRT rear-projection television sets (the Diamond and now defunct Platinum series sets) and Pioneer's Elite line of rear-projection televisions.

Sylvania/Magnavox clones. LaserStack held up to 10 discs and could automatically load or remove them from the player or change sides in around 15 seconds. A version for the

Although the X9 has auto-reverse, the X0 offers a picture with less noise and better color rendering than any other player.

The 7820 was the only player ever sold to either the industrial or consumer market that was entirely designed and engineered by the technicians at MCA Disco-Vision and contained all of their preferred design approaches, such as playing the disc with the laser on top (instead of underneath) and moving
309:
MCA DiscoVision had no suggested retail price for the PR-7820; depending on the number purchased, it varied from $ 3,500 to $ 2,200 per unit if more than 1000 were bought at once. Fully functional 7820s are not easily available on eBay and are nearly impossible to find in fully functional condition.
305:
The 7820 was the first LD player to use solid-state tangential tracking: instead of a tangential tracking mirror, the 7820 used an electronic CCD delay line to provide tangential tracking corrections, giving the player superb color quality. It was not until 1985/6 that the tangential mirror began to

Most LaserDisc players required the user to manually turn the disc over to play the other side. A number of players (all diode laser based) were made that were capable of playing both sides of the disc automatically; at the end of the first side, or at the viewer's command, the machine would reverse

Only one consumer player, the LD-W1 (it was also released industrially too), was made that could hold more than a single disc; the W1 held two discs and could automatically change discs and sides by rotating the entire mechanism, including both the laser and turntable. Electrically, the LD-W1 was

In March 1984, Pioneer introduced the first consumer player with a solid-state laser, the LD-700. It was also the first LD player to load from the front and not the top. One year earlier
Hitachi introduced an expensive industrial player with a laser diode, but the player, which had poor picture

Most players made after the mid-1980s were capable of also playing audio CDs. These players included a 4.7 in (12 cm) indentation in the loading tray, where the CD would be placed for play. At least two
Pioneer models (The CLD-M301 and the CLD-M90) also operated as a CD-changer, with

While Pioneer produced some industrial "jukeboxes" that held more than 50 discs, one company offered, for a short time in 1984, a "LaserStack" unit that required the user to physically remove the player lid for installation and attached to the top of the Pioneer LD-600, LD-1100 or the

Pioneer continued to sell the player under the Pioneer name as the Pioneer Model-III. The unit was a full Level-III player and could accept a data-dump from discs themselves. It could also be controlled by an external computer and could be gen-locked to external video sources.

In addition to the advanced comb filter, the HLD-X0 and HLD-X9 contains a red-laser pickup, which significantly reduces crosstalk and picture-noise levels compared to players with the traditional infrared laser; it can also read through all but the worst cases of

Certain Japanese models of Pioneer players are considered by enthusiasts to be of higher quality or capable of higher-quality playback than North American models. These include the CLD-R7G, LD-S9, HLD-X9 and HLD-X0.

The Pioneer DVL-909 lacks support for DTS output. However, a modification to the player can allow this player to support DTS streams on DTS discs, essentially turning the DVL-909 into a Pioneer Elite DVL-91.

computer interface box was also made available at the same time which contained additional memory that increased the total size of a disc-based computer program the 7820 could store and execute to 256k.
