ABSTRACT:
It is intended to shorten the read time after receiving a read command. The method comprises step S2 for determining whether or not a read request address for a new read command is identical to an address being currently read, step S4 for, if they are identical, outputting CD-ROM stored data RD held in a memory as read data against the read command after completion of the current read process, and step S6 for, if they are not identical, performing a seek operation, performing a read process after completion of the seek operation, and outputting the read data after completion of the read process.
