DISC CARTRIDGE HAVING SENSOR HOLE TO BE OPENED/CLOSED AND APPARATUS AND METHOD FOR DRIVING THE SAME.

摘要

DISCLOSED IS A CARTRIDGE (10) HAVING SENSOR HOLE (24) TO BE OPENED/CLOSED AND METHOD AND APPARATUS FOR DRIVING THE SAME. THE INVENTION AIMS TO CURE THE PROBLEM IN WHICH WHEN A CARTRIDGE HOUSING A DVD-RAM DISC HAS ONCE BEEN OPENED AND THE DVD WITHDRAWN THERE FROM, REPRODUCTION/RECORDING APPARATUS PERFORMS THE RECORDING PROCESS UNDER THE SAME CONDITIONS AS IT WOULD WITH A BARE DISC INCLUDING UNNECESSARY VERIFICATION PROCEDURES. THE DISCLOSED CARTRIDGE (10) HAS A MEANS FOR OPENING/CLOSING A SENSOR HOLE (24) TO ENABLE USER CONTROL OF OPENING/CLOSING OF THE SENSOR HOLE IN ACCORDANCE WITH RESULT OF A DEFECT CHECK. BY GIVING THIS EXTRA USER CONTROL, INFORMATION PROCESSING PROCEDURES MAY BE MUCH ACCELERATED. (FIGURE 2)
