    摘要： A reproducing apparatus and method for reproducing recorded information recorded on an information recording medium. A drive is provided for reproducing the recorded information from the information recording medium. A non-volatile memory is provided for memorizing at least two informations, each including an identifier of the information recording medium, and position information indicative of a position on the recording medium, where the drive is reproducing, while maintaining correspondence with each other therebetween. A controller is provided for deciding on whether the identifier is memorized or not in the non-volatile memory, which is coincident with an identifier reproduced from the information medium by the drive previously. The recorded information is reproduced from the information recording medium loaded onto the drive.

    摘要： Programs or data in a mask ROM incorporated in a one-chip microcomputer can be modified from the outside. With version information appended to each of a mask ROM 2 incorporated in a one-chip microcomputer 6 and an external EPROM 5, by comparing the version numbers, programs (tasks and subroutines) of a new version can always be executed and update data of a new version can be used. The programs can be customized for each user.

    摘要： 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).
