摘要： The present invention provides a measure for getting read/write control information stored within a space of a predetermined size in a format that ensures compatibility with media of a lower order or an older generation even if the size of the read/write control information increases significantly as the storage densities of information storage media rise in the near future. On an information storage medium, a data sequence is writable as a combination of marks and spaces. The medium has at least one information storage layer, which has an information storage area to store information and a control information area for use to perform a read/write operation on the at least one information storage layer. The control information area stores at least one set of control information, which includes a first kind of write pulse information including information to be used as a reference value and a second kind of write pulse information including information to be used as an offset value. If the pulse width or pulse position of a write pulse is definable with a precision of 1T/n (where T is a channel clock pulse width and n is a positive integer), the size of the offset value is large enough to define at least an n/2 range.

摘要： An information storage medium according to the present invention has n information storage layers (where n is an integer and n≧3), on which data can be written with a laser beam and which are stacked one upon the other. Each of the n storage layers has a test write zone for determining the recording power of the laser beam. When those n layers are counted from the one that is located most distant from the surface of the medium on which the laser beam is incident, there is a bigger radial location difference between the outer peripheral end of the inner one of the test write zones of ith and (i+1)th information storage layers (where i is an integer that satisfies 2≦i≦n−1) and the inner peripheral end of the other outer test write zone than between the outer peripheral end of the inner one of the test write zones of jth and (j+1)th information storage layers (where j is an integer that satisfies 1≦j≦i−1) and the inner peripheral end of the other outer test write zone.

摘要： The present invention has an object of evaluating a recording and reproduction signal quality of a high density information recording medium by providing an index representing, in a detection signal including a plurality of pieces of edge shift information, how each edge is shifted. A signal evaluation method, usable for an information recording medium having a data sequence including a mark and a space located alternately, for generating a binary signal from a signal obtained by reproducing the data sequence using a PRML signal processing method and evaluating a likelihood of the binary signal, includes a differential metric calculation step of calculating, from the binary signal, a differential metric which is a difference of a reproduction signal from a first state transition matrix having a maximum likelihood and a second state transition matrix having a second maximum likelihood; and a step of classifying the differential metric to any of a plurality of data patterns each including at least one mark and at least one space. The data pattern classification to any of the plurality of data patterns is performed using a combination of a length of a first mark included in the data sequence and a length of a first space adjacently located immediately previous or immediately subsequent to the first mark, and is further performed using a length of a second mark which is not adjacent to the first mark and located adjacent to the first space; and thus a reproduction signal quality of the information recording medium is evaluated.
