Patent ID: 8488420

Claim:
An apparatus for recording data on an information storage medium having a plurality of recording layers, the apparatus comprising: a pickup configured to radiate a beam or receive the beam to transmit data with respect to the information storage medium having a physical ADIP address (PAA) which corresponds to an address recorded on the information storage medium; and a control unit configured to determine an address to which the pickup will move during an interlayer movement to record data, and control the pickup to record the data; wherein, an address of a layer i to which the pickup will move corresponds to PAAi, an address of a layer j in which the pickup is currently located corresponds to PAAj, and n corresponds to the number of the recording layers, the control unit determines whether the PAAi and the PAAj satisfy the equation PAA i = PAA j +(7−( i+j ))*40 00 00 h+ 00 00 01 h ( i+j =odd and i,j= 0,1,2 , . . . ,n −1) in response to the pickup moving from an even layer to an odd layer or from an odd layer to an even layer, and whether the PAAi and the PAAj satisfy the equation PAA i =PAA j +( i−j )*40 00 00 h ( i+j= even and i,j= 0,1,2 , . . . , n −1) in response to the pickup moving from an even layer to another even layer or from an odd layer to another odd layer.
