Patent number: 7525892Abstract: A method of erasing an erasable disc. When an optical drive is erasing a DVD-RW disc, a write mode, instead of a conventional erase mode, is used to execute an erase operation. In the write mode, the invention sets current values of individual current paths in a laser diode drive circuit such that a laser diode always outputs a constant erase power (Pe) onto the DVD-RW disc-no matter how a write pulse signal changes. Thus, after a starting position of the DVD-RW disc is determined, the optical drive only needs to write a data amount of n ECC blocks to complete the disc erasing operation without continuously detecting the LPP (Land Pre-Pit) data block to obtain a stop erasing position on the disc in the conventional optical drive.Type: GrantFiled: June 2, 2005Date of Patent: April 28, 2009Assignee: Lite-On It CorporationInventors: Yi-Shih Wang, Kuo-Chiang Chang, Ling-Feng Chen
