DUAL STRIPE OPTICAL DATA CARD. |
摘要 |
An optical data card having a pair of spaced apart information strips. One strip has pre-recorded programs or data and is always a non-erasable strip. This strip may be either a reflective direct-read-after-write non-erasable type or may be a read-only optical memory (ROOM) strip. Another strip serves as a temporary, scratchpad or cache memory and is either a reflective DRAW strip of the erasable type or a DRAW non-erasable strip which is at least partially blank, with sufficient space for temporary memory needs over an extended period of time. |
