Embodiment Construction

[0047] Next, examples of the present invention will be described. The relationship between the structural elements described in the claims and the embodiments of the present patent application is as follows. This relationship indicates that examples supporting the claims of this patent application are described in the embodiments of this patent application. Therefore, even if examples corresponding to the embodiments are not described in this section, the examples should not be construed as structural elements that do not correspond to the claims of this patent application. On the contrary, even if examples are described in this section as corresponding to structural elements of the claims, the examples should not be construed as not corresponding to structural elements other than the structural elements of the claims of this patent application.

[0048] In addition, the description in this section does not mean that all aspects of the invention corresponding to the examples ...

Abstract

It is possible to improve the user-friendliness of a recording medium and easily perform reproduction processing. When reproduction processing (123) for reproducing the material data recorded on a disc (32) is performed, a disc information file management section (63) references a reproduction history of the disc information file held in a disc information file holding section (52) and starts reproduction of the material data according to the reproduction history. When the reproduction processing is complete, the disc information file management section (63) updates the reproduction history of the disc information file held in the disc information file holding section (52). A disc information file recording control section (82) records the updated disc information file on the disc (32).

Description

technical field [0001] The present invention relates to an information processing device and method, a program, and a recording medium, and in particular, to an information processing device and method, a program, and a recording medium that allow reproduction processing and the like to be performed more easily than before. Background technique [0002] Conventionally, material data such as video data and audio data that are photographed and recorded are recorded on a magnetic tape device such as a video tape as a recording medium. In other words, when a user moves material data from a first device to a second device, the material data is moved through the tape device. [0003] In the magnetic tape device, material data is recorded along the time axis which is the longitudinal direction of the magnetic tape. Therefore, when the first device (at a position in the middle of the material data) stops reproduction of the material data and the second device resumes reproduction f...
