CODE DECIDING DEVICE AND METHOD, RECORDING MEDIUM DISCRIMINATING DEVICE AND METHOD AND INFORMATION RECORDING DEVICE AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide a code deciding device, etc., surely deciding the presence of identification information ought to be recorded in an area excepting a data area and reflecting the decision result to following recording processing. SOLUTION: This device is provided with a pickup 11 optically detecting an information code at least containing the identification information for individually identifying a recording information writable optical disk DK itself from the optical disk DK and a system controller 19 moving the pickup 11 onto an initialization area being the area on the optical disk DK on which the information code should be recorded and deciding whether or not the information code is recorded on the optical disk DK based on a detection signal Spp outputted from the pickup 11 moved onto the initialization area.
