Patent ID: 8649653

Claim:
A playback device, comprising: a platform on which applications are executed; an I/O module operable to provide an application loaded from a first recording medium with a function of accessing recording media; a player operable to play back data; a playback controller operable to read data from the first recording medium and supply the read data to the player, in response to a playback request issued by the application through the I/O module; and a copier operable to read data from the first recording medium, and copy the read data into the second recording medium without passing through the I/O module, in response to a copy request issued by the application, wherein when the application issues the copy request for commencing copying of the read data into the second recording medium while playback of the read data is performed, the playback controller and the I/O module both transition to a rejecting state of rejecting a request for data of the first recording medium from the application before copying of the read data is commenced, and while copying of the read data is performed, the application performs processing that is executable without using the first recording medium.
