<p>PCT No. PCT/JP96/03194 Sec. 371 Date Sep. 23, 1997 Sec. 102(e) Date Sep. 23, 1997 PCT Filed Oct. 31, 1996 PCT Pub. No. WO97/17652 PCT Pub. Date May 15, 1997An information processing apparatus and information processing method enables a write once type disc to 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. In addition, by monitoring the writable residual capacity, the recording medium can record data which is made or being updated in the memory.</p> |
