    摘要： The present invention controls to read encrypted digital data from a detachable storage medium, in which the digital data and a decode key for decoding encryption of the digital data are stored. In reading the digital data, the decode key is read, the decode key is deleted from the storage medium, the encrypted digital data is read, and then encryption of the encrypted digital data is decoded by the read decode key.

    摘要： This invention provides a technique that deletes data at high speed, and prevents discontinuous cluster chains from being produced due to data deletion. To accomplish this, when data included in the data file is partially deleted from the head of the data file, the location of header information is moved for respective clusters, and the size of the header information is changed, so as to start head data after data deletion from the location immediately after the moved header information.

    摘要： A recording apparatus includes a recording unit configured to record moving image data including a plurality of frames on a recording medium. The recording medium includes a plurality of clusters. The apparatus also includes an editing unit of the moving image data, a setting unit configured to optionally set the editing unit, a management information processing unit configured to generate management information including link information indicating a cluster number of the moving image data to be reproduced next with respect to a plurality of clusters having the moving image data recorded thereon, and a control unit configured to control the recording unit to record a front frame of each editing unit in the moving image data on an area beginning with a cluster of the recording medium based on the editing unit set by the setting unit.
