摘要： An magneto-optical memory device for recording, reproducing or erasing information by applying an optical beam such as a laser beam onto a magneto-optical recording medium, the magneto optical memory device including a recorded region detecting circuit for detecting information recorded region formed in the recording medium. In the memory, a timing control for recording, reproducing or erasing is performed with the use of one result obtained through detection of a synchronizing signal such as a sector mark indicative of a starting point of an information block and another result obtained through detection in the recorded region detecting circuit. The recorded region detecting circuit comprises a pair of peak hold circuits for detecting a peak levels of the playback signals and first and second selecting circuits for selecting one of the reproduced signals and for selecting one of two reference voltages with different voltage levels, respectively smoothing the playback signal, and a comparator for comparing the outputs of the first and second selecting circuits.

摘要： A data modulation/demodulation system reproducing data that is divided and recorded in a plurality of blocks on a recording medium. The data modulation/demodulation system utilizes the steps of modulating the data by adding specified data bit patterns to the data bits of each block and reproducing the data which have been obtained by adding specified code bit patterns. The bit rows are independently demodulated by demodulation clocks which differ in phase. The demodulation bit pattern of the above code bit pattern which was added at the time of recording and the bit pattern which was demodulated by the different modulation clocks are compared with each other to determine which data is wrong. The correct demodulated data is selected according to this comparison and transmitted.

摘要： A optical disk recording and reproducing device capable of recording and reproducing data to or from an optical disk. Continuous signals representing continuous analog information such as audio and video information and discrete signals representing discrete data-information such as numerical data including program codes or character data are recorded dividedly in different recording regions provided on an optical disk including erasable or write once-type disks. The optical disk is rotated at a given linear or rotary angular speed under control by a disk rotation control device so as to simplify rotational control of the optical disk in accessing the information in the divided regions.
