DATA READING APPARATUS, DATA READING METHOD, DATA READING CONTROL APPARATUS, PROGRAM AND RECORDING MEDIUM

摘要

This invention provides an optical disc driving apparatus (100) in which an ATAPI I/F (160) receives a command, such as a SWITCH command including volume designation information that designates the volume of the BD-RE layer or BD-ROM layer of a BD hybrid disc (300). If the ATAPI I/F (160) accepts a READ command by receipt of the next SWITCH command after the receipt of the foregoing SWITCH command, a system control unit (110) reads data from the volume designated by the volume designation information included in the received SWITCH command.
