There is provided an information processing apparatus which records data in a recording medium including: a recording section which records data in the recording medium; a detecting section which detects continuous or fragmented free areas in minimum allocation unit of the recording medium; and a recording control section which controls the recording section so that the recording section sequentially records data in the continuous free areas of the recording medium detected by the detecting section, and at the time point when the recording is completed, the recording section moves an end portion of the recorded data to the fragmented free areas of the recording medium detected by the detecting section so as to be recorded.

Information processing apparatus, recording method, and computer program

A recording-and-reproducing apparatus for managing content data recorded on a removable recording medium includes: a device configured to acquire reproduction information required for reproducing the content data; a device configured to generate a first management file for individually managing the content data; a device configured to register control information for the content data in a second management file collectively managing the content data. Further, the apparatus includes a device configured to read out the control information in the second management file recorded on the recording medium; a memory in which the control information of the second management file read out by the read-out device is expanded; a device configured to compare the control information in the second management file expanded in the memory and the content data recorded on the recording medium; and a device configured to update the control information in the second management file expanded in the memory.

Recording-and-reproducing apparatus and content-managing method

A recording-and-reproducing apparatus for reproducibly controlling data recorded on a recording medium includes: a device configured to acquire control information required for reproducing the data when the data is recorded; a device configured to control operations during the period from the start to the end of recording data on the recording medium. The apparatus further includes a device configured to determine whether a recorded file of the data exceeds a predetermined limit of a storage capacity of a file system in the recoding medium and sequentially generate a subsequent recorded file upon exceeding the limit. Moreover, the apparatus includes a device configured to generate a single recording-and-reproducing unit during the period on the recording medium indicated by the control device based on a plurality of recorded files upon exceeding the limit; and a device configured to update the control information by recording the single recording-and-reproducing unit on the control information.

Recording-and-reproducing apparatus and recording-and-reproducing method

An apparatus for holding a recording medium that contains an engagement member backwards with respect to an insert direction thereof has a main body containing an insert portion through which the recording medium is inserted on one end thereof and an eject portion on the other end thereof. The inserted recording medium are ejected from the eject portion with it being linked with an insert of the recording medium from the insert portion. The apparatus has a first engagement device that engages the engagement member of the recording medium when the recording medium is inserted by a predetermined position to hold the inserted recording medium. The apparatus has a second engagement device that engages the engagement member of the recording medium when the recording medium is ejected from the ejection portion to hold the ejected recording medium.

A switch has a detection portion that contains a magnetic-field-sensing element and an attraction member. The attraction member generates a magnetically attracting force. The detection portion generates a switching signal based on an output of the magnetic-field-sensing element.

Switch and recording medium

A system and method to facilitate editing of content data. An update metadata identification block identifies metadata that is affected (or must be updated) by destructive edit processing by a material data destructive edit processing block. If the metadata is required for updating, a realtime metadata update block updates realtime metadata and a nonrealtime metadata update block updates nonrealtime metadata in correspondence with the destructive edit processing. A proxy data update block updates proxy data. A clip information file update block updates a clip information file. A clip write block records the data of each clip updated by the above-mentioned processing to an optical disc.

Information processing apparatus and method and program

The present invention provides a recording and reproducing apparatus for recording and reproducing any of video data, audio data, and realtime metadata corresponding to any of the video data and the audio data by use of a random-accessible recording medium. The recording and reproducing apparatus executes destructive editing on any of video data, audio data, and realtime metadata corresponding to any of the video data and the audio data recorded on the random-accessible recording medium on the recording medium.

Recording and reproducing apparatus, and editing method

In a storage disk control apparatus, a load of a computer caused by transferring data is reduced, and a waiting time until a data transfer operation is commenced is shortened. In the disk control method for controlling a disk apparatus including a disk having a plurality of storage regions for storing data therein by way of an external apparatus external addresses produced from the external apparatus are related to internal addresses indicative of positions of the storage regions the external addresses are converted into the internal addresses related thereto, and the disk is accessed based on the internal addresses. In the disk control apparatus for controlling a disk apparatus including a disk having a plurality of storage regions used to store therein data, there are provided management means for managing a correspondence relationship between external addresses and internal addresses indicative of positions of the storage regions, and conversion means for converting a preselected external address into the internal address related thereto by the management means and for supplying the converted internal address to the disk.

Disk control method and control apparatus capable of lowering data

A method and apparatus for controlling the access to a recording disk which determines a skew so that a rotational delay time at an average distance of movement when a head accesses the recording disk is minimized. The methods and apparatus determine the position of a data block on the recording disk based on at least the determined skew, schedules an order of a plurality of input disk access requests so that an amount of movement of the head becomes small at the time of access with respect to the recording disk by the head, and the head accesses the recording disk based on the result of the scheduling.

Methods and apparatus for controlling access to a recording disk

Data transmitting apparatus and method of same

A parallel arithmetic-logical processing device in which arithmetic-logical processing is shared among and executed in a parallel fashion by a plurality of processing elements. The device includes a large-capacity serial access memory for continuous reading/writing of large-scale data, a small-capacity serial access memory for continuous reading/writing of small-scale data and a high-speed general-purpose random access memory for random writing/readout of small-scale data. A central processing unit (CPU) causes the memories to be used or not used depending on the scale of the arithmetic-logical processing. Since the serial access memory executes continuous data writing and reading, high-speed access may be achieved, so that it can be manufactured inexpensively with a large storage capacity. Consequently, the processing speed in the CPU may be increased, while the parallel arithmetic-logical processing device may be manufactured inexpensively.
