Disclosed herein is an information processing apparatus that processes an encrypted content. The apparatus includes a control section configured to control the following processes, such as a generation process, a moving range determination process, a holding process, a copying process, and an inactivation process. Such processes are to be performed independently in a specified order as a process for achieving moving out of at least a part of the encrypted content from a moving source to a moving destination.

Information processing apparatus and method, and a program

A schedule-controlling unit selects a file whose remaining time for playback is the shortest among files to be restored and compares the remaining time for playback of the selected file with a reference time set in advance. When the remaining time for playback is longer than the reference time, the schedule-controlling unit again selects a file in which a distance parameter of a partition of unrestored data to be subsequently restored is the lowest among files to be restored. A restoring unit restores unrestored data of one partition of the file selected by the schedule-controlling unit.

Recording and playback apparatus and recording and playback method

Hard disk drive unit with buffer and cue data areas efficiently records files to magnetic tape. Recording and reproducing apparatus includes changer unit for selecting and carrying tape cassettes and accommodating magnetic tapes with predetermined recording areas, tape drive unit for loading tape cassettes and recording and reproducing magnetic tapes, hard disk drive unit having a buffer area for recording and reproducing data in the tape drive unit, and controller unit for managing recording areas of tape cassette magnetic tapes arranged in the changer unit as a continuously formed area. Storage level is set corresponding to remaining capacity of buffer area and remaining capacity of one BOF data area, or number of past access times to corresponding file in a file information table and final access time, etc. Based on storage level, control operations are performed. Frequently used file data can be selectively recorded to buffer or BOF data areas.
