Information processing apparatus, imaging apparatus, information processing method and computer program

An information processing apparatus for mitigating the processing load of its CPU to increase the transfer rate at recording and enhance the usage efficiency of recording media. A host CPU determines whether an information signal supplied from the apparatus is a moving picture signal according to an instruction entered by user through a key operation block or according to the information included in the supplied information signal. If the supplied information signal is found to be moving picture information, the CPU detects free blocks each made up of a plurality of clusters by referencing the FAT information of a hard disk and records the moving picture information in unit of detected free blocks. If the supplied information signal is found not to be moving picture information, the CPU records the detected signal to free clusters on a cluster basis.

Data recording apparatus, data recording method, and program

A recording device which records data onto a recording medium includes a nonvolatile memory storing and holding data on a free capacity of the recording medium, and a control unit controlling the data recording. The control unit determines the free-capacity data stored in the nonvolatile memory based on the total capacity of the recording medium when power is turned on. When the determination result indicates that a value of the free-capacity data stored in the nonvolatile memory does not exceed a value of the total capacity of the recording medium, the control unit records the data onto the recording medium with reference to the free-capacity data. When the power is turned off, the control unit updates the free-capacity data so as to reduce the value of the free-capacity data by as much as an amount of the data recorded onto the recording medium.

Information processing equipment is so constructed that the power consumption of a disk drive for hard disks, optical disks, or the like can be reliably and sufficiently reduced. The host CPU () of an information processing unit () forms a command for changing the power consumption mode of a HDD () based on the state of control on the HDD (). The host CPU supplies the command to the HDD () through a media controller (). When the HDD () accepts the command, it changes its power consumption mode according to the instruction from the information processing unit. Thus, the information processing unit can control the power consumption mode of the HDD () based on the state of control on the HDD ().

Information processing apparatus, imaging apparatus, information processing method, and computer program

A recording/reproducing apparatus in which the number of revolutions of a recording head 14 is controlled depending on the frequency of the vertical synchronization signals for picture signals supplied from outside for digitally recording/reproducing picture data. It is not the recording head 14 but the playback head 16 whose number of revolutions is controlled in such manner during reproduction. In forming DRCK control signals employed for controlling the number of revolutions of the recording head, the frequency of the vertical synchronization signals for the picture signals supplied from outside is corrected so as to be within a range of offset of .+-.1% relative to the frequency of standard frequency vertical synchronization signals, and the DRCK control signals are formed based upon the vertical synchronization signals corrected in this manner. This permits picture data to be recorded so as to assure interchangeability between different apparatus of the same version, and makes it possible to improve the stability after phase capturing of, for example, a DRCKPLL circuit 34 designed to form the DRCK control signals.
