摘要： PROBLEM TO BE SOLVED: To provide a signal recoder and a signal recording method for recording dynamic images of a movie, etc., without certifying an optical disk recording medium. SOLUTION: A record part 10 of a signal recoder 1 records dynamic image data on an optical disk. A defective sector detecting circuit 31 reads a physical block address corresponding to a logic block address of the receded dynamic image data from a recording medium, and detects an address error. If the address error is detected, an address control circuit 32 stops read-counting from a RSPC(Reed Solmon Product Code) working memory 14. After the defective sector detecting circuit 31 detects an address error, if detecting a sector of an excellent physical block address, the circuit 31 supplies a restart signal to the address control circuit 32 to start recording from this excellent sector. A RAM 24 stores the physical block address of a defective sector and records all the dynamic data, and then this list is recorded in a recording medium.

摘要： PROBLEM TO BE SOLVED: To drastically improve access speed on the discoid recording medium by reading out a restoring data held in a storage means at and after the second read time and outputting this data as a reproducing data. SOLUTION: This is the reproducing method of an optical disk for the purpose of restoring a data having an incorrigible error by using a parity sector. When a read-out data at the first read time becomes incorrigible, by using a parity sector corresponding to this defect, a data of this sector is restored, and this data is held in a buffer memory 64, and information in the buffer memory 64 is registered as a table data 63b. At and after the second read time, a cached sector data is restored by a CPU 60 using a parity sector data, and a restored data registered in a chache table data 63c is read out. Thus, the access speed on the recording medium can drastically be improved.

摘要： PROBLEM TO BE SOLVED: To efficiently carry out a process of reproducing a rewritable disk by a read-only disk drive.SOLUTION: A WBBM is recorded in a read-in area of a rewritable disk. The WBBM is a bitmap indicating a recorded/unrecorded state for each block which is a recording/reproducing unit. To enable the read-only disk drive to perform seek and to stabilize servo, finalization is carried out by recording dummy data in the periphery of a recorded block. At this time, the efficiency of the process can be improved by referring to the WBBM. By forming a plurality of WBBMs in a ring structure, and sequentially updating the WBBMs, writing concentration on the same area can be prevented, and the destruction of the WBBM by blackout or the like can be compensated for. The latest WBBM can be displayed by the value of an update counter.

摘要： PROBLEM TO BE SOLVED: To enable accurate recording and reproducing clocks to be generated by making constant the line density for the wave number regarding wobbling waveform of a track and forming a rotation angle mark indicating a prescribed rotation angle position of a disk. SOLUTION: Data are recorded while keeping constant line density(CLD), and the number of carrier waves of a wobbling group is assumed to CLD, further, a fine clock mark is added as CAV reference, and record and reproduction being more accurate are aimed at, and the wobbling period of a group is set. First, in adjacent tracks, the phase relation of a wobbling waveform is made so that a rotation angle position to be fixed relation exists. For example, when a rotation angle position of a start point of each rotation track is assumed to be 0 degree (the direction of 12 o'clock of a clock), the phase difference between adjacent tracks is made to have fixed relation at this position 0 degree. Further, a fine clock mark is added to a rotation angle position in fixed relation when phase difference is 0, 180, or 270 degrees.

摘要： PURPOSE: To save resources by recording correct data to be recorded in a defective area in an alternate area set in a recordable area and dispensing with the scrapping of a disk shaped medium in the case a defect is present in a reproducing only area. CONSTITUTION: In a step S122, whether an alternate sector is present or not is judged and when a judged result is 'YES', the step is moved to a step S123 and when it is 'NO', the step is moved to step S126. In this step S122, whether the alternate sector is present or not is judged by SDL information read in a step S121. In a step S125, the rear part of an alternated sector is read to be transferred to a host computer. Then, the step is returned to a step S120 again to perform the waiting of a read command. In the step S125, data obtained by reading the sector of the next sector movement of a defective sector are transferred to the host computer.

摘要： PROBLEM TO BE SOLVED: To efficiently carry out a process for reproducing a rewritable disk by a drive for a read-only disk. SOLUTION: The recording device records a WBBM (written block bit map) on read-in areas of the rewritable disk. The WBBM is a bit map showing the recorded/unrecorded state for every block which is a unit of recording/reproducing operation. A seek is attainable by the drive of the read-only disk, and a finalization for recording dummy data near the recorded block is carried out for stabilizing a servo. At this time, the efficiency of the process can be improved by referring the WBBM. By forming a plurality of WBBMs in the ring structure and successively updating the WBBMs, a concentration of the write-in to the same area is prevented, and a compensation to a destruction of the WBBM due to a power failure, etc., is attained. A latest WBBM can be shown by an updated counter value. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a finalization method capable of reproducing an optical disk such as a DVD(digital video disk)-RAM, etc., by a reproducing device performing CLV(constant linear velocity) reproduction. SOLUTION: This finalization method is realized by processes from a step S10 to the step S70. That is, the unrecorded area map of the optical disk is formed on an LBA(logic block address) (S10-S30). For performing conversion from the LBA to a PBA(physical block address) normally performed in an optical disk drive by application of a host side, a conversion table from the LBA to the PBA is formed (S40). Based on this conversion table, the unrecorded area map is converted from the LBA to the PBA (S50), and the area to be fanalized is decided (S60). The dummy data are recorded on the decided area on the optical disk (S70).

摘要： PROBLEM TO BE SOLVED: To enable the rotary control of a disk in which data are intermittently recorded in a CLV reproducing device. SOLUTION: When a recorded area in which data are substantially recorded and a non-recorded area in which data are not substantially recorded exist in an optical disk 1 intermittently, dummy data are recorded in the non-recorded area, the non-recorded area is reproduced continuously after the recorded area, a clock is extracted and the rotation of the optical disk 1 is made controllable. Consequently, runaway of a spindle motor is prevented.
