DATA RECORDING/REPRODUCING DEVICE, DATA RECORDING/REPRODUCING METHOD, PROGRAM AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a stable system capable of reducing the influence of a disturbance, etc. SOLUTION: A stable data reproduction is carried out by attaining the error correction to a random error or burst error in a larger extent by using a first error correction coding unit and a second error correction coding unit, without lowering a transfer speed by avoiding the retry operation. The constitution of an error correction block is set so that a sector (C2 sector) with the second error correction code becomes a first read-out sector at the movement to a certain track by a seek operation.
