摘要： A disc apparatus in which recorded data can be correctly reproduced despite occurrence of a low-reliability area at a specified position on a disc on which synchronization signals are recorded. A comparison error signal between the playback RF signals read out from a disc 100 and channel clocks PLCK enters a VCO 15 via a phase/frequency comparator 12. A VCO 15 generates PLCK at a frequency corresponding to the voltage of the comparison error signal. A data detection unit 16 takes out data from the playback RF signals. If a Sync pattern detection interpolation unit 17 detects the Sync pattern correctly from this data, the above comparison error signal is directly fed to the VCO 15 and, if otherwise, the sample-and-hold unit 14 holds the voltage of the comparison error signal by control signals from a controller 20. At this time, interpolation of the Sync patterns by the Sync pattern detection interpolation unit 17 is discontinued.

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： A recording medium of the recordable type in the form of a multi-layer disc or the like which is improved in compatibility and feasibility in use and a recording apparatus and a recording method ready for the recording medium are disclosed. A region for recording interlayer folding back position information is set on the recording medium (for example, “End sector number in Layer 0” or a session item type 3). In response to a fact that recording on a certain recording layer reaches a maximum recording range or that data recording advances from a certain recording layer to a next recording layer, interlayer folding back position information is recorded on the recording medium. This signifies that such recording is performed when advancement of the data recording to another recording layer is performed at a stage prior to disc closing or session closing or when it is predicted that such advancement of the data recording occurs soon. Also where the disc is of the type for which multi-session recording is performed, interlayer folding back position information is recorded with regard to a session in which folding back is performed.

摘要： The amount of light reflected from a disk is detected, and it is determined according to the amount of reflected light whether the disk is a recordable disk or a rewritable disk. The disk is controlled according to the result of determination such that it is rotated at a constant angular velocity (CAV) or at a constant linear velocity (CLV) and recording is executed. Further, rotation driving control of the disk is selected according to factors other than the type of the disk, such as according to whether random recording is allowed or not, according to a recording state in the disk, according to whether an alternative area is provided or not, according to a recording start position, or according to whether initialization is required or not. CLV control or CAV control is appropriately selected for a disk at recording to suppress a reduction in accessibility and a reduction in data transmission rate.
