摘要： A recording device according to the present invention has a function (202, 206, 207) of dividing precoded record data into data blocks of a prescribed length to adjust to a magneto-optical disk (3) and adding an intrinsic pattern before and after the data blocks. As the intrinsic pattern, a pattern which reduces a decoding error of maximum likelihood decoding at an end of each data block is used. Therefore, even when data is inserted after preceding, code correlation of a precoded signal can be maintained at a location where division is performed.

摘要： A read out apparatus reads out prerecorded information from a magneto-optic disk by detecting intervals of edges of magnetic domains formed on the magneto-optic disk with different directions of magnetization, where the intervals of the edges of the magnetic domains correspond to data "1"s or "0""1"s of the prerecorded information. The read out apparatus includes a first part for producing a read out signal by scanning the magnetic domains of the magneto-optic disk, a second part for producing an edge detection signal which has rising and falling edges depending on leading and trailing edges of the magnetic domains, and for corecting edge positions of the edge detection signal based on predetermined information, a third part including a phase locked loop circuit for producing a clock signal which is synchronized to the rising and falling edges of the edge detection signal, and a fourth part for separating the data from the edge detection signal output from the second part using the clock signal output from the third part.
