Abstract: PROBLEM TO BE SOLVED: To provide a disk device capable of reproducing recorded data correctly even though an area where the reliability of data is low is generated at a specific position being on a disk where a synchronizing signal is to be recorded. SOLUTION: The comparison error signal between the reproduced RF signal read out from a disk 100 and a channel clock signal PLCK is inputted from a phase/frequency comparing part 12 to a voltage controlled oscillator(VCO) 15, which generates a PLCK with a frequency in accordance with the voltage of the comparison error signal. In a data detecting part 16, data are taken out from the reproduced RF signal. When a sync pattern is detected from the data correctly in a sync pattern detecting and interpolating part 17, the comparison error signal is inputted to the VCO 15 as it is and when it is not detected correctly, a sample-and-hold part 14 holds the voltage of the comparison error signal by a control signal from a control part 20. At this time, the sync pattern interpolating operation of the sync pattern detecting and interpolating part 17 is suspended.

Abstract: PROBLEM TO BE SOLVED: To increase a capacity of a rewritable disk, by providing first, second and third regions as units for recording or reproducing data and respectively defining a length thereof. SOLUTION: A first region is a cluster, a second region is a link frame, and a third region is a link data area. The clusters are coupled to each other by the link frame. The link frame is provided therein with a postamble, a postguard, a Slice/PLL area as well as the link data area. In the link data area, data which is substantially identical with that to be recorded in the cluster is recorded. Thus, a region of the link data area where the data is recorded or reproduced is defined in the link frame. As a results, a capacity of a rewritable disk can be increased while retaining compatibility with a read-only disk.

Abstract: PURPOSE:To smoothly reproduce a next music without an interruption equivalent to a required access time, or through a continuous or with a constant no sound period. CONSTITUTION:An access operation takes place when the data reading of a third music from a recording medium such as a disk is completed, move a pickup 2 at an eighth music during a time Ta. While reading the data of the eighth music, store the data which are read from the recording medium on a buffer memory 6 and read the data with a delay time Td which is longer than the access time Ta. During the access time Ta, the data of the previous third music from the memory 6 are read so as to keep the reproduction. Immediately after the completion of the reading of the third music or after a constant no sound period T0, the data of the eighth music are read.

Abstract: PROBLEM TO BE SOLVED: To realize a quick access to a disk and high speed reproducing and to improve error correcting capability. SOLUTION: Data are recorded on an optical disk 1 by adding double parities namely, inner parity and outer parity, to them. The inner parity is added to the data which are interleaved, and is used to correct inner codes. The outer parity is added to the data which are not interleaved and the inner parity and is used to correct outer codes. Reproduced data from the disk 1 are supplied to a ring buffer memory 5 to be stored, and supplied also to an error correcting circuit 71 where the outer codes are corrected. The corrected results are supplied to the memory 5 and overwritten. The data stored in the memory 5 are again read by the circuit 71 and the inner codes are corrected. Data whose outer codes are corrected are used for the detection of sector addresses in a sector detecting circuit 72. During special reproducing, only the outer code correction is conducted.

Abstract: PROBLEM TO BE SOLVED: To identify whether a signal recorded in a signal recording medium is an original signal or a copied one, by recording in a medium a video signal and/or an acoustic signal into which an identification signal is inserted. SOLUTION: A video signal inputted to a terminal 1 is inputted to an addition circuit 3 via an A/D converter 2, and an identification signal is added to the least significant bit of the luminance signal of the digital video signal inputted from the terminal 28. The signal is provided with compression encoding in a compression encoding circuit 4 according to MPEG 2 Standard and is sectored in a sector circuit 5, which adds an error detection sign to the signal. After a header is added to the signal in an addition circuit 6, a parity bit is added to the signal in a encoding circuit 7, and the signal is then converted into modulated data of 16-channel bit in a modulation circuit 8, and a synchronizing signal of an out-of-rule pattern is added in an addition circuit 9 and the signal is recorded in an optical disk 12 with a recording/reproducing head 14.
