摘要： A recording medium as a physically rewritable disk is appropriately used as a write-once type. In order to use the rewritable media in write-once applications, the recording medium in the data structure thereof includes, in a second data unit (an ECC block of 64 Kbytes), flag information WF1-WF4 indicating whether a first data unit (2 Kbytes) is stored. More specifically, whether a plurality of first data units (a sector handled by a host) has been recorded in the second data unit (a recording unit sector on the recording medium) is directly indicated. When an access request is issued in emulation in a disk drive device, the flag information is referenced, and the disk drive device determines whether one of writing or reading of the first data unit as a target responsive to a command is enabled.

摘要： In an information reproducing apparatus employing a maximum likelihood decoding method such as Viterbi decoding, there is a problem such that power consumption increases because a maximum likelihood decoding circuit is complicated, and many circuit elements must be used. A clock output control means is provided on a read clock transmission line of a maximum likelihood decoder, and no read clock is supplied to the maximum likelihood decoder in operation modes other than a specific operation mode when an input data is decoded by a Viterbi decoder, and thereby, it is possible to greatly reduce a power consumption. More specifically, in operation modes other than the read mode, the supply of read clock is stopped by the clock output control means based on a control signal from a controller for controlling an operation mode such as decoding or the like.

摘要： In a magneto-optic disc apparatus corresponding to six-value four-status Viterbi decoding method, an RAA has 12 registers so as to separately adapt amplitude reference values for an address portion and amplitude reference values for a data portion on a magneto-optic disc. Normally, stored values of the registers at the time a reproducing operation has been just completed are used for initial values for an adapting process in the next reproducing operation. On the other hand, when data cannot be correctly reproduced and thereby a read-retry operation or the like is preformed, predetermined values that are stored in 12 registers in the RAA are used as initial values. In this case, the adapting process for amplitude reference values is not performed.

摘要： A disk recording medium has reliability of address reading which is maintained equivalently to the conventional disk recording medium by recording a first address and a second address that are identical in a header area. By arranging the first and second addresses to be reversely displaced from the center line of a groove track or a land track to the radial direction of the medium, the distance between the first and second addresses when they are adjacent is increased, which eliminates the influence of crosstalk. This avoids redundancy of the header area and enables high-density recording to the disk recording medium.
摘要翻译：磁盘记录介质通过记录在标题区域中相同的第一地址和第二地址，具有与常规盘记录介质相当的地址读取的可靠性。通过将第一和第二地址从凹槽轨道或槽脊轨迹的中心线反向移动到介质的径向方向，第一和第二地址相邻时的距离增加，这消除了影响的串扰。这避免了头部区域的冗余，并且能够对盘记录介质进行高密度记录。
