ABSTRACT:
An optical disk structure for an erasable optical disk for use with an erasable optical disk drive using electron trapping optical memory media is disclosed in which several distinct layers in additon to the electron trapping optical memory media are utilized in order to minimize light scatter between adjacent tracks on the disk and to carry permanent format and guidance information for use in accomplishing the write, read and focusing and tracking functions of the erasable opticl disk drive with which the disk structures are utilized. The use of absorbing layers as part of the optical disk structure for attenuating reflections of light within the disk structure and eliminating the spreading of marks is also disclosed.
