摘要： Disclosed is a method for recording and reproducing sector control information to and from a novel magneto-optical disk to which the so-called erasure type data reproduction method or data-embossed type reproduction method applies. On the magneto-optical disk, sector control information is recorded onto a sector control information recording region at a track recording density lower than that of a data recording region. When data is recorded on the disk at a high track density, the sector control information is recorded in such a manner that the information will not exist on adjacent tracks along the same radials of the disk.

摘要： A method for reproducing a magneto-optical recording medium the recording pits of which are erased or relieved with rise in temperature of the recording medium caused by radiation of a readout beam, or an optical recording medium the reflectance of which is changed with rise in temperature of the recording medium caused by radiation of the readout beam, in which changes in the size of an effective reproducing region due to the temperature of the magneto-optical or optical recording medium may be inhibited. To this end, a temperature sensor 20 for sensing the temperature of the magneto-optical disc 11, for example, is provided and the laser power or the external magnetic field is controlled depending on the detected temperature by the temperature sensor 20 to maintain a constant size of the effective reproducing region at all times.

摘要： The present invention provides an apparatus and a method for precisely and adequately evaluating actual quality of reproduced data whenever applying a maximum likelihood decoder for converting signal reproduced from a recording medium into binary signal. Based on data arrays of a pair of binary data outputted from a “Viterbi” decoder, SAM values are secured by selecting any of path-metric differential values (00) and (11) being the difference between a pair of values compared when renewing path-metric values PMM (00) and (11) outputted from the “Viterbi” decoder. The minimum SAM value for an ideally-reproduced signal is outputted from a constant generating circuit. If the SAM values are verified as valid, and yet, if the SAM values coincide with the equation “input SAM values”≦“data value outputted from the constant generating circuit”, then squared values outputted from a square circuit are averaged by an averaging circuit. Finally, the average value is outputted as the reproduced signal evaluation.

摘要： In a data decoding apparatus of this invention, level of a reproduction RF signal 7a at the time of the binary level judgment of channel bit is temporarily stored into a RF signal level memory section 20. The portions which do not satisfy the conditions of the minimum run length and the maximum run length of the same symbols within the channel bit data train are respectively detected by a (d'-1) detecting section 16 and a (k'+1) detecting section 17. This data decoding apparatus comprises correction bit position detecting sections 18, 19 for outputting correction bit position designation signals on the basis of level of the RF signal at the time of the binary level judgment stored in the RF signal level memory section 20, and a bit data inversion correcting section 15 for inverting logic level of data at bit position designated on the basis of the correction bit position designation signals 18a, 18b, 19a, 19b. In the case where there exists any portion which does not satisfy the conditions of the minimum run length and/or the maximum run length of the same symbols within channel bit data obtained by binarizing a signal which has been read out from the recording medium, correction is implemented to the channel bit data, thereby making it possible to improve the bit error rate, and to ensure skew margin.

摘要： An encoder/decoder device for improving the bit error rate, speedily and at low cost without using an A/D converter circuit. A comparator compares the playback signal loaded from the disk with a specified reference level, places the signal in binary notation and sends the binary information to a memory. When the continuous length showing the quantity of zeroes placed between ones in succession is an error length which is shorter than a specified length 3T designated beforehand, an error length detection circuit detects this as a continuous length. A pattern detector circuit detects patterns in which the continuous length in front of error length 2T is 3T and the continuous length behind 2T is 4T or more, and further detects patterns in which the next continuous length after error length 2T is 3T and the continuous length in front of 2T is 4T or more. A position compensator circuit specifies the bit right after 2T as the correction position when a pattern greater than 3T-2T-4T is detected; and specifies the bit right before 2T when a pattern greater than 4T-2T-3T is detected. A processing circuit inverts the logic of the bits specified for position correction and outputs the result.
