Abstract
A drive unit connecting system for connecting a drive unit for an optical information/data recording medium to a reproducing apparatus serving as a destined host apparatus through the medium of a general-purpose interface is designed to inhibit normal operation when the drive unit is connected to other apparatus than the destined one without employing expensive IC chips dedicated for authentication. The drive unit connecting system enables a drive unit to be connected to only a proper reproducing apparatus through a general-purpose interface by performing software-based processing on either one of command(s) or parameter(s) or alternatively on both of the command(s) and the parameter(s).
