Abstract: PURPOSE:To immediately execute driving at a constant linear speed at the time of activation, etc., by comparing a reproducing wobble signal with a prescribed reference signal and controlling a spindle motor at the constant linear speed until a data signal is exactly fetched. CONSTITUTION:A first spindle servo circuit 30 inputs a 1/12 dividing 30A signal of a wobble signal SWB to a phase detecting circuit 30B. A 1/4 dividing 30C signal of a reference clock CKSB is inputted to the circuit 30. The circuit 30B compares the both signal and sends a compared result to an input edge (a) of a switching circuit 32 as a spindle servo signal SBSP1. A second spindle servo circuit 31 inputs a 1/3 dividing 31A signal of a bit clock CKBIT to a phase detecting circuit 31B. The signal CKSB is inputted to the circuit 31B. The circuit 31B sends the compared result of the both signals to an input edge (b) of the circuit 31 as a spindle servo signal SBSP2. A switching control circuit 34 selects the input edge (a) of the circuit 32 when a CRC error is detected by prescribed times on the basis of a CKC error flag FGCRC but otherwise the input edge (b) is selected.

Abstract: PROBLEM TO BE SOLVED: To easily set and change the marker of a recording medium.
SOLUTION: An address on a disk corresponding to a position decided as an editing point in a buffer memory is detected. By recording the detected address on the disk as the editing point in the disk, work until the establishment of an editing point is carried out by using the address in the memory, and the position of the established editing point is obtained as an address on the disk. The editing point decided by the address in the memory is converted into an address on the disk, and then recorded in the disk. Thus, the editing point is easily decided and changed without repeating a reproducing operation each time.

Abstract: PROBLEM TO BE SOLVED: To perform reproduction together with recording data by securing the recording area of additional data in a reproduction exclusive area where recording data with a data structure being the same as that of a recording and reproducing area is recorded. SOLUTION: Digital data is made into a block at every prescribed number of sector to form a cluster, a connection sector being longer than an error correction interleaving length is disposed at every cluster connection part and, then, recording is performed in a disk shape recording medium. A cluster address for identifying the cluster and a sector address for identifying each sector in the cluster are previously formatted and recorded in the medium.

Abstract: PROBLEM TO BE SOLVED: To provide a recording and reproducing device and a recording and reproducing method by which both of the track name and the next are recorded by automatically copying the track name or the text to the text or the track name as to an optical disk where only either of the track name or the text of audio data is recorded. SOLUTION: The recording and reproducing device is provided with a microcomputer 13 that discriminates whether a track name of audio data or a text is recorded and generates one on the basis of the other when one of them is recorded, a memory control circuit 10, and a RAM 11 and records the generated track name or text onto an optical disk 20. Thus, the track name or the text is automatically generated to an optical disk to which the text or the track name is not recorded so as to save the trouble of data entry.

Abstract: PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which an economical burden is reduced by a method wherein auxiliary data is read out from a copy source disk, so as to be stored in a storage region and the auxiliary data is recorded, from the storage region, in a copy destination disk, which is loaded after the copy source disk is discharged. SOLUTION: Auxiliary data on a static image or the like which becomes an auxiliary data file which is independent of data on a piece of music or the like as a program is recorded in copy source disk 90, in addition to the data on the piece of music. As the recording region of the auxiliary data, 38 clusters are prepared inside a U-TOC, and the auxiliary data is JPEC- compressed and recorded here. When the copy source disk 90 is placed, a system controller 11 reads out the auxiliary data so as to be retained in a buffer memory RAM 13. After the copying operation of the auxiliary data is instructed, the copy source disk 90 is replaced by a new disk to be copied. Then, the system controller extracts desired data from the data in the RAM 13, and the data is recorded in a space area inside the U-TOC on the copy source disk 90, which is placed at present.

Abstract: PROBLEM TO BE SOLVED: To provide a recording/reproducing system having a high function expansion capability and good operability. SOLUTION: A data file as sub-data on characters, images or the like is recorded together with main data as a program in a recording medium. The date file as the sub-data is recorded in a particular area (AUX data area) as a sub-data area. Also, this data is managed independent of the program based on sub-data management information. Further, by the management system of the sub-data management information, data in a certain data file is outputted by a timing matched with an output timing in a particular program.
