Stabilizing holographic disk medium against vibrations and/or controlling deflection of disk medium

摘要

The present invention relates to: stabilizing a holographic disk medium against vibrations by engaging at least one of surface of a disk medium when coupled to a disk medium coupler and during recording or reading holograms to or from the disk; stabilizing the disk medium proximate the outer peripheral portion thereof, coupling and uncoupling the disk medium to and from the disk medium coupler and causing the stabilizing means to engage the disk medium when coupled to the disk medium coupler; imparting an axial offset proximate the peripheral portion to deflect a record and/or read portion of the disk medium towards a normal record and/or read plane when coupled to the disk medium coupler, and optionally stabilizing the disk medium against vibrations; and stabilizing the disk medium against vibrations when rotatably mounted on or within a data storage cartridge.
