摘要： If there is any portion in channel bit data obtained on converting a signal read out from a recording medium into a bi-level signal which fails to satisfy a condition concerning a minimum run length or a maximum run length of the same symbol, the channel bit data is corrected to improve the bit error rate to secure a skew margin. To this end, channel bit data not satisfying a minimum run length d' of the same symbol is detected by a (d'-1) detector 4 using n-tupled clocks obtained on n-tupling channel clocks of playback data by a bit clock generator 2, where n is an integer not less than 2. A correction position of the channel bit data having the run length of the same symbol equal to (d'-1) is designated by a correction bit position designating unit 5. A data correction unit 6 then corrects the channel bit data so that the minimum run length of the same symbol will be equal to d'.
摘要翻译：如果在将从记录介质读出的信号转换成不能满足与相同符号的最小游程长度或最大游程长度有关的条件的双电平信号中获得的通道位数据中存在任何部分，则通道位校正数据以提高误码率以确保偏斜裕度。为此，由（d'-1）检测器4检测不满足相同符号的最小游程长度d'的通道位数据，使用通过位时钟在重放数据的n个tupling通道时钟上获得的n个元组时钟发生器2，其中n是不小于2的整数。具有相同符号的游程长度等于（d'-1）的通道位数据的校正位置由校正位位置指定单元5指定。数据校正单元6然后校正通道位数据，使得相同符号的最小游程长度将等于d'。

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： A magneto-optical reproducing apparatus for reproducing from a magnetic film medium having at least a displacement layer, a switching layer, and a memory layer. A magnetic wall displacement is generated in the displacement layer in any region where the temperature exceeds the Curie temperature of the switching layer to effectively enlarge any recorded magnetic domain. The reproduced signal from the magnetic film medium is equalized with regard to waveform in an equalizer circuit and then fed to a magnetic wall displacement detection circuit that produces a magnetic wall displacement signal by using a differential signal or a secondary differential signal of the reproduced signal so as to provide a low bit error rate despite any sudden DC level variation in the reproduced signal.
