Esoteric P-700

 High-precision mechanism featuring VRDS

In our newl developed Vibration-Free Rigid Disc Clamping System mechanism, the slighty concave turntable is above the disc which is held against it by upward pressure exered by a large-diameter disc clamper, for higher stability. This new disc clamping system, with the disc held tightly between the turnyable which has the same diameter as the disc and a precisely aligned clamper, corrects any  warping or eccentricity of the disc, so that the microscopic pits are always traced accurately by the center beam of the laser pickup. Another advantage of the system is that it minimizes any undesirable vibrations of the disc.

Newly developed floating suspension system for the ultimate stability.

The optical system and the mechanism which supports it are the most important parts of any CD player, and are critical if it is to operate at peak performance. In the CD Drive Unit, the laser pickup drive system uses a newly developed floating suspension which completely isolates it from internal resonance, external vibrations and any influence of external sound pressure, so it can read the digital signals from the microscopic pits with high precision and extreme stability.

High-prcision 3-beam linear tacking laser pickup for ultimate tracking ability.

The 3-beam linear-tracking laser pickup was newly developed to have the lightest possible weight and excellent rigidity. Together with the newly-developed disc clamipng system using a large turntable, it gives the drive an extremely precise pit tracking ability.

High-rigidity dual-construction chassis

The unit has the ideal anti-resonance heavy-weight dual construction chassis. As the shaved-aluminum front panel is combined rigidly with the thick chassis, the overall construction is solid and has superior non-resonationg characteristics. Moreover, since this CD Drive Unit does not incorporate the D/A converter section, it offers extra rigidity; vibrations and mechanical oscillations from the player cannot interfere with the operation of the D/A converter.
