Patent ID: 7385898

Claim:
An apparatus to determine an area of an optical disc efficiently, comprising: a pickup that reads/records a signal from/to the optical disc; a spindle motor that revolves the optical disc; and a controller that determines whether current time information of the pickup is greater than or equal to 95 minutes, where current time information is less than or equal to 95 minutes, determines a logical block address of the pickup, and where current time information is greater than 95 minutes, counts a number of absolute time-code in pre-groove (ATIP) syncs for one rotation of the optical disc at a current position of the pickup, compares the number of counted ATIP syncs with a reference number of ATIP syncs, and where the number of ATIP syncs is less than or equal to the reference number of ATIP syncs, determines that the pickup is in a lead-in area, and where the number of ATIP syncs is greater than the reference number of ATIP syncs, determines the logical block address of the pickup, wherein the optical disc has an absolute time of 99 minutes, and wherein the controller comprises: a memory that stores a reference number of ATIP syncs for each track of the optical disc; a counter that counts the number of ATIP syncs for each track at the current position of the pickup; and a location determination unit that compares the number of counted ATIP syncs with the reference number of ATIP syncs and determines the logical block address of the pickup to reduce access time.
