ABSTRACT:
In an optical disk drive, upon each power on or disk receipt, a mode control is set to non-operate, i.e., no commands can be received unless a mode setting command has been received. All other commands are rejected for preventing any access to an optical disk present in the drive until after a mode setting command has been received. When a mode set command is received after a power on or after each disk receipt, the mode control is set to operate which allows receipt and execution of legal commands. The mode setting requirement forces selection of write verify or not and to turn laser off or not after a predetermined time delay after completing a last command.
