A BD-ROM playback apparatus simultaneously executes reproduction of a title including an AVClip and executes an application. The BD-ROM playback apparatus includes a BD-J module ( 35 ) executing an application, a playback control engine ( 32 ) for playing the AVClip belonging to one title, and a module manager ( 34 ) for controlling branching between a plurality of titles. The title includes a data management table. The data management table indicates an application read priority level for each title. The BD-J module ( 35 ) includes a java virtual machine ( 38 ), a local memory ( 29 ), and an application manager ( 36 ) for loading the application to the local memory ( 29 ). The application manager ( 36 ) reads in the application into the local memory ( 29 ) according to the read priority level of each application and the memory size of the local memory ( 29 ).
