OPTICAL DISK REPRODUCTION DEVICE, OPTICAL DISK REPRODUCTION METHOD, AND OPTICAL DISK REPRODUCTION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an optical disk reproduction device which handles the bend of an optical disk. SOLUTION: A detector 6 measures an ambient temperature of an optical disk reproduction section 2. A storage section 4 stores the temperature values measured at a plurality of different positions on the optical disk being reproduced by the optical disk reproduction section 2, and at a plurality of time points which have different temperatures, in association with a focus drive voltage of the optical disk reproduction section 2. A reproduction controller 3 performs reproduction control on the optical disk in the optical disk reproduction section 2 with an approximation expression using the measured values stored in the storage section 4.
