  • Patent number: 8346051
    Abstract: A recording and reproducing apparatus (100) can record information on a recording memory (111) having a recording region where a smallest unit for erasing recorded information is a block, on a unit of a cluster that is a unit smaller than the block. The recording and reproducing apparatus (100) includes: an input unit (130) that receives a request for starting or ending recording a file; and a system control unit (101) that records a header section of the file and a data section following the header section, from the beginning of the block in the recording region, when the request for starting recording is received; and updates the header section and records the updated header section on another cluster different from the cluster on which the header section before update is recorded when the request for ending recording is received.

  • Publication number: 20120210077
    Abstract: A recording system includes a controller configured to write content data on at least first and second storage media, in parallel with each other. If there is a period in which the content data has failed to be written on the first storage medium but has been written successfully on the second storage medium, the controller finds, on the first storage medium, a storage space, of which the size is equal to or greater than that of partial data that is the content data that has been written successfully on the second storage medium during the period, and writes recovery information on one or more storage media other than the first storage medium. The recovery information includes some pieces of information to identify the first storage medium, to specify the storage space, and to define an area on the second storage medium on which the partial data has been written.

  • Publication number: 20050286855
    Abstract: The present invention is a data recording device that can record data at a high speed into a semiconductor memory pack device including a plurality of flash memories that operate in parallel. The data recording device that records data into the semiconductor memory pack device including the plurality of flash memories that perform recording operations in parallel is provided with a file management portion for managing data that is to be recorded into the semiconductor memory pack device as a file, in which the file management portion sets a data recording unit of data that is to be supplied to the semiconductor memory pack device to a common multiple of a size obtained by adding up the sizes of the erase blocks of the plurality of flash memories and a data management size (a cluster size) of the file management portion.
