Abstract
An improved configuration for the Philips Air Sandwich Disk' is described that is compatible with high speed, high density recording. Major advantages include: improved balancing capability, more accurate and repeatable self-centering on the turntable spindle, flatter substrate profile during rotation, and relatively simple assembly without the requirement for accurate substrate tolerances. The centrifugally induced pressure gradient within the rotating air cavity and how the improved design deals with this phe-nomenon is addressed.
