Abstract
The present invention discloses a method and system for providing defect management of a bulk data storage media wherein logical addresses of media data blocks are continuously slipped to omit all media data blocks determined to be defective at the time of an initial media format. Thereafter, selectable parameters are utilized to define a logical zone including both a user data area and corresponding replacement data area on the media such that proper selection of the parameters provides defect management optimized for a particular use of the media.
Claims7
An information storage media adapted to provide media data storage area management, the storage media comprising:
- a primary list including information identifying media data sections initially determined to be unacceptable, wherein a logical address hierarchy which omits physical address information of the media data sections initially determined to be unacceptable is determinable from the primary list, and wherein the logical address hierarchy determined from the primary list is continuously slipped across the media to omit the unacceptable media data sections;
- a spare interval parameter establishing a number of media data sections associated with a user data area on the media;
- a spare length parameter establishing a number of media data sections associated with a sparing data area on the media, wherein the number of media data sections established by the spare length parameter may be zero, and wherein the spare interval parameter and the spare length parameter are selectable independently of geometric characteristics of the media;
- at least one user data area including the number of media data sections established by the spare interval parameter, wherein the media data sections of the user data area excludes sections identified in the primary list;
- at least one sparing data area including the number of media data sections established by the spare length parameter, wherein the media data sections of the sparing data area excludes sections identified in the primary list;
- and
- a secondary list including information identifying each media data section of the sparing data area and providing information with respect to the status of each media data section of the sparing data area.
