摘要： An optical disk recording thereon compressed moving picture data and an optical disk reproduction apparatus each capable of easily effecting trick play such as high speed reproduction and a retrieval operation at a high speed. Additional information necessary for trick play is recorded in an arbitrary area of an optical disk such as a TOC (Table of Contents) or a leading sector (sector 0) of the disk, and a sector address is added to each sector. To conduct trick play, an I picture, a P picture and a B picture contained in a GOP layer inside a bit stream of compressed image data are extracted and reproduced in accordance with a reproduction speed by looking up a trick play table.

摘要： A disk cartridge and a disk device for receiving the disk cartridge to enable recording and/or reproducing of information from or on a disk housed within the disk cartridge. The disk cartridge includes a disk in which information is recorded and/or reproduced, a case for housing the disk which case has opposite faces including a window in a respective face for exposing a part of the disk therethrough. A shutter is mounted with respect to the case so as to open or close a window of a respective face of the case with the shutter being movable in opposite directions with respect to the window from a position in which the window is closed to a position in which the window is open. The disk cartridge may include an openable part of the case for enabling the disk to be taken in and out of the case through the openable part thereof and a discrimination arrangement for enabling discrimination of different types of disk cartridges from one another. The disk cartridge may be arranged to enable exchange of disks of a same or different format including CD (compact disk), DVD (digital video disk) and PD (phase change disk) and the discrimination arrangement enables prevention of a disk cartridge of one different type from being erroneously inserted into a disk device receiving apparatus which is not compatible for the different type of disk cartridge.

摘要： An apparatus for recording and reproducing a burst-like digital information signal, and a method capable of predicting the time of occurrence of a header indicating the beginning of the first data of a digital information signal during its reproduction from a recording medium. The digital signal includes a plurality of data blocks, each including a first header indicative of the head of the block, and each first header including the address of the block. During recording of a digital signal on the recording medium, a plurality of second headers, which are substantially the same as the first headers of the data blocks and including addresses having given relations with the addresses of the data blocks, are inserted in a clock regenerating signal recorded before the digital signal for regenerating the clock for the signal. The second headers are inserted at a period equal to the period of each data block so as to be synchronized with the headers of the data blocks.

摘要： An apparatus for recording and reproducing a video signal and a PCM audio data sampled by a sampling frequency being asynchronous to a field frequency of a video signal. The apparatus enables to record and reproduce the digital data formatted at each field. The apparatus includes an address control circuit for switching the number of sample values to be recorded per field and a clock generating circuit. The clock generating circuit provides a VCO for forcibly stopping the switching of the number of the sample values, keeping the number of the sample values constant and generating a sampling clock being synchronous to a field frequency, based on a signal sent from an input terminal for a selecting signal. When recording a different digital data from the PCM audio data, the sampling clock sent from the clock generating circuit is used in the address control circuit.
