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

The information recording apparatus records unit information which includes recording information including, for example, video and audio data and reproduction control information for the reproduction on a rewritable-type recording medium. After information is recorded, temporary management information for all the unit recording information recorded on the recording medium is produced and is recorded on the recording medium. By producing temporary management information and recording it on the recording medium every time new unit recording information is recorded on the recording medium, it becomes possible to reproduce the respective unit recording information from the recording medium by referring to the temporary management information. If an access error such as a writing error or a verify error occurs at the time of recording the temporary management information at the temporary recording position, that position is not used anymore and the temporary recording position of the temporary management information is changed or shifted.
