INFORMATION PROCESSING APPARATUS AND METHOD

摘要

An information processor and a method of information processing wherein a write once type disc can be used as a rewritable recording medium. There can be realized an address control mechanism wherein even if the physical recording position is changed, the logical address of the same block is not changed by controlling the physical recording position on the recording medium on an imaginary address space in correspondence to the logical address. Thus the write once type recording medium can be realized as a rewritable recording medium.
