ABSTRACT:
A single beam direct read during write and write protect system for use in an optical data storage system. The optical data storage system includes a reflective-type optical disk, a laser for producing a beam of radiation to write data onto the optical disk during write operations, and a radiation detector for producing write detect signals representative of radiation detected from the optical disk during the write operations. A slope detector produces verification signals indicative of the accuracy of the write operations as a function of a slope of the peaks of the write detect signals. A digital counter is enabled by the verification signals, and produces a write error signal when a predetermined number of inaccurate write operations are detected.
