Method of processing data of defect sector in a DVD-RAM system and the DVD-RAM system

摘要

A method of processing data of a defect sector in a DVD-RAM (Digital Video Disk-Random Access Memory) system and the DVD-RAM system. In the method, a defect list is read from a lead-in area of a DVD-RAM disk during playback of the disk. The defect list is stored in a predetermined area of a memory of a signal processing portion in the system while the predetermined area of the memory is not full and a remaining part of the defect list is stored in an ATAPI (AT Attachment Packet Interface) buffer memory once the predetermined area of the memory is full. A sector having the title of a user-input file is searched, a physical sector address for the searched sector is designated, the defect list is read, and it is determined whether the physical sector address is in the defect list. Then, sector data corresponding to the physical sector address is stored in the memory of the signal processing portion if the physical sector address is not in the defect list, and otherwise, no sector data corresponding to the physical sector address is stored in the memory.
