Abstract
An accessible count information which is the number of accessible times for recording medium is recorded on an additional recording dedicated area in the recording medium. Each time the recording medium is accessed, the accessible count information is subtracted and the value of remaining accessible count information is recorded in a non-recorded portion of the dedicated area. In this case, the access to the recording medium is controlled based on the minimum value of the accessible count information recorded in the dedicated area.
