INFORMATION RECORDING MEDIUM, RECORDING/REPRODUCING APPARATUS AND RECORDING/REPRODUCING METHOD

摘要

An information recording medium, a recording and/or reproducing apparatus and a recording and/or reproducing method are provided. The recording apparatus includes: a write/read unit for recording data on an information storage medium in which a user data area for writing user data and a spare area for replacing a defect occurring in the user data area are disposed, and a replacement recording block to replace an original recording block recorded in the user data area is recorded in a non-recorded area of the spare area or the user data area; and a control unit for controlling the write/read unit so that a replacement entry indicating that part of the recording block is replaced is recorded on the storage medium. As a result, data reproduction time can be advantageously reduced so as to improve system performance, particularly, in a system where data replacement by logical overwrite (LOW) is implemented both in a user data area and a spare area, or in a system performing defect management.
