Claim:
1. A playback device comprising: a virtual-package-data file system processor to treat a combination of first data recorded in a first recording unit and second data recorded in a local storage area in a second recording unit including the local storage area and an application data area as virtual package data and performs reading and writing of the virtual package data; a file system processor to perform reading and writing of application data recorded in the application data area; a playback controller to control playback of the virtual package data; a processing execution unit to process the application data; and a data access controller to cause the virtual-package-data file system processor to perform reading or writing of the virtual package data according to a first access request from the playback controller, the first access request requesting reading and writing of the virtual package data, and to cause the file system processor to perform reading or writing of the application data according to a second access request from the processing execution unit, the second access request requesting reading or writing of the application data; wherein in a case where the first access request from the playback controller is a request for requesting reading or writing in the local storage area, the data access controller causes the virtual-package-data file system processor to perform the reading or writing of the virtual package data with priority over the reading or writing of the application data by the file system processor.
