Abstract

A transferring operation for music contents can be simplified. In addition, a check-out can be performed without destruction of a data structure of music contents. A personal computer 100 manages music contents with an album composed of entities of songs and a play list composed of pointers to entities of songs. When songs are checked out from the personal computer 100 side to a disc drive device 1 side, all songs contained in albums described in a play list are checked out. In addition, the play list is transferred to the disc drive device 1 side. The transferred play list and songs that have been checked out are linked. Thus, the numbers of permissible check-out times for songs become the same in each album. As a result, the transferring operation for music contents can be simplified and a check-out can be performed without destruction of the data structure of music contents.

Description

technical field [0001] The present invention relates to a data transfer system, a data transfer method, and a data transfer program, and more particularly, to a method of transferring music content from a personal computer to a portable recording and reproducing device, and from a portable recording and reproducing device to a personal computer. A data transfer system, a data transfer method, and a data transfer program. Background technique [0002] In recent years, portable recording and reproducing devices capable of recording and reproducing music and the like, having an internal hard disk drive, and being miniaturized have appeared. Such a portable recording and reproducing device is connected with a personal computer in order to manage music data recorded in the device. [0003] For example, much music data is stored on the internal hard drive of a personal computer. Music data constitutes a database. A personal computer constitutes a music server. Music data is us...
