摘要： A recording and reproducing system which uses a recording medium having a plurality of information recording tracks for recording image information. And at least one index recording track is located on the recording medium for recording index information. The index recording track is located substantially at the center of the recording medium and extends length wise of the recording medium in the direction of movement of this recording medium. Accordingly, the recording medium of the present invention eliminates the adverse effect of the drop-out and reduces the period of time required to search for the index information and reproduce image information.

摘要： Channel data obtained from a reproduced signal is input to a demodulation ROM as an address and demodulated. In the demodulated channel data, the data whose data pattern is not consistent with a 2-7 modulation method is recognized as an error data. When a resync code, given in the channel data at every 15 bytes is not detected within a predetermined time period, a resync code undetected signal is generated. The demodulated data is arranged in a matrix, and the position of the error data in the matrix and the resync code undetected generation position are specified. An error correction circuit carries out the error correction (erasure correction) by using these positions and an error correction code relating to one direction of a row or a column of the matrix.
摘要翻译：从再现信号获得的信道数据作为地址被输入到解调ROM，并进行解调。在解调的信道数据中，其数据模式与2-7调制方法不一致的数据被识别为错误数据。当在预定时间段内没有检测到每15个字节的通道数据中给出的再同步码时，产生重新同步码未被检测的信号。解调的数据被排列成矩阵，并且指定矩阵中的错误数据的位置和重新同步代码未检测的生成位置。误差校正电路通过使用这些位置和与矩阵的行或列的一个方向相关的纠错码执行纠错（擦除校正）。

摘要： In a device for recording or reproducing information by using a light beam, there is provided an optical disk comprising a base plate, a recording layer formed on the base plate, tracks provided for recording information on the recording layer, and a focus check area for checking if the light beam is focused at the optimum position on the recording layer when an optical head which generates the light beam faces the recording layer. Accordingly, it is possible to change the focus position for the recording layer of the optical disk by the objective lens of the optical head during recording and reproducing information. Also, it is possible to set it at a position where the bit error rate is smallest and has a wider margin for the shaft of the adjust position.

摘要： A data recording apparatus has an optical scanner for optically scanning a document and for outputting an image signal corresponding to the document pattern, a modified Huffman coding circuit for compressing the image information output by the optical scanner for each scanning line, and a page buffer memory for storing the image signal compressed by the modified Huffman coding circuit as line image information items. The line image information items are read out from the page buffer memory in units of a fixed number of bits, and are divided into image data pieces of a fixed bit length. Dummy data is added to the terminal end image data which does not have the fixed bit length, thus forming a terminal end image data of the fixed bit length. Error correction data is set for each image data piece.

摘要： The recording scheme of an optical disk is initially determined by a cartridge identifier housing the optical disk. The optical disk is then rotated at a rotational speed corresponding to the initially determined recording scheme, and a signal processing circuit is switched. Management data recorded on the optical disk is read to also determine the recording scheme, thereby improving the reliability of the determination. When no management data can be read, a recording scheme and associated rotational speed are changed. The management data representing the recording scheme is then read according to the changed recording scheme. A medium type determined based on the management data has priority over that of the medium type obtained by the identifier of the cartridge.
