    摘要： A rewritable recording medium and a recording method wherein a train of clock pulses for PLL synchronization, which is to be inserted in a sync pulse interval consisting of at least one horizontal scan period and different from the vertical blanking period of a video format signal, is subjected to biphase modulation with a time code and is recorded, by the superimposition on the video format signal, on the recording medium. According to the second aspect, in a rewritable recording medium having pregrooves, lands serve as record tracks, and odd track numbers and even track numbers are respectively recorded in odd track number areas and even track number areas in each sector of the pregrooves, so that in writing data or reading data from an odd or even track, a corresponding odd or even track number can be obtained.

    摘要： A NAND flash memory has memory cell transistors which data is written into. If number of times the program operation has been executed is not equal to the prescribed upper limit number of times, then the program voltage is set so as to be raised by a first potential difference and then the program operation and the verify operation are executed again, andonly when the number of times of the program operation has become equal to a prescribed number of times being less than the upper limit number of times, the intermediate voltage is raised by a second potential difference and fixed.

    摘要： A rotary video head type information recording/reproducing apparatus in which a video tape runs while being in contact with a stationary head at the time of fast-feeding/rewinding of the video tape. In recording/reproducing operation of the information recording/reproducing apparatus, a one-scene picture is extracted at intervals of a predetermined period from a picture signal and the extracted picture is recorded on the video tape by the stationary head in synchronism with the picture signal. When it is desired to perform a picture search, a still picture which changes at intervals of the predetermined period can be reproduced on a picture screen of a display only by performing the fast-feeding/rewinding operation. Accordingly, an operator can perform search for a desired picture at a high speed by referring to the timing of change of the still picture actually displayed on the picture screen.

    摘要： For recording and reproducing analog audio signals by a pulse-code modulation scheme so as to permit effective compensation for dropout errors, an incoming audio signal is sampled, and the analog samples are converted into a sequence of coded pulse groups or words. These words are grouped into successive notional blocks, and the odd and the even words, for example, of each block are divided into sub-blocks, as by sequentially writing the words of each block in successive storage locations in a memory and by retrieving the odd, and then the even, words from the memory. The sub-blocks of the successive word blocks are recorded in different regions on a recording medium such as magnetic tape. After being reconverted into an electrical signal from the recording medium, the words of the sub-blocks of each block are rearranged into the original order, as by use of a second memory, prior to the reconstruction of the analog audio signal.
