摘要： PROBLEM TO BE SOLVED: To exclude a remainder of erase of a substrate at the editing from the object for the C2 correction without inserting an EditID into an ID of a SYNC block or preparing a reproduction system for detecting the EditID of the substrate, in a reproducing apparatus provided with such a non-tracking reproduction method that a same track is scanned by one reproduction head in multiple times, a C1 correction is executed to data reproduced by each scan for every predetermined recording block, the C1-corrected reproduced data are written into a memory, and two corrections are executed to the reproduced data read out from the memory. SOLUTION: A part of tracks at the back side among the tracks of predetermined number of pieces becoming an editing unit SG is set in an ahead-write priority area SG2 and the remainder is set in a post-write priority area SG1, and a discrimination is made whether the reproduced data in the recording block of the same ID as the recording block are being written in the memory with respect to each recording block which is reproduced from the ahead-write priority area SG2 and C1-corrected, then the reproduced data of the recording block not being written are written into the memory, and the reproduced data of the recording block being written are not written into the memory.

摘要： PROBLEM TO BE SOLVED: To secure off-track margin by detecting segments to be processed and performing correctly error correction for reproduction data of the segment to be reproduced.
SOLUTION: Two reproducing heads are provided in the direction of track width deviating their positions for the track for each track of four tracks traced simultaneously, and reproduction data REa-1, REa-2 are generated for one track. In the same way, reproduction data REb-1, REb-2, REc-1, REc-2, REd-1, REd-2 are generated. A segment detecting part 71 extracts segment discrimination information for each reproduction data, detects a target segment from the extracted segment discrimination information, and supplies segment discrimination information SIDg of the target segment to a correction control part 72. The correction control part 72 controls write-in and read-out of reproduction data for a memory 722 so that error correction using reproduction data of a segment being different from the target segment is not performed in a C2 correction processing part 73.

摘要： PROBLEM TO BE SOLVED: To enable performing interchange-reproduction without deteriorating sound quality when normal reproduction is performed.
SOLUTION: Video data Vin having a frame frequency of 23.97 Hz is recorded in a tape 120, corresponding to it, audio data Ain having a sampling frequency of 48 KHz also is recorded. In the audio data Ain, sample data of 1001 pieces are recorded for each field. At the time of normal reproduction, video data Vout having a frame frequency of 23.97 Hz is reproduced from the tape 120. At the case, a rate converter 137 outputs audio data of each field keeping the number of the sample data at 1001 pieces. At the time of interchange-reproduction, video data Vout having a frame frequency of 25 Hz is reproduced from the tape 120. At the case, the rate converter 137 outputs audio data of each field converting the number of the sample data from 1001 pieces to 960 pieces.

摘要： PROBLEM TO BE SOLVED: To suppress deterioration of sound quality caused by that sample data of the different prescribed time is mixed to audio data of the prescribed time in reproducing of variable speed. SOLUTION: A reproducing head scans three times on a tape for each field. A sync-block which is supplied from a Ci decoder 162 and in which an error is corrected is written in a SDRAM163. In the case, a scan number indicating that reproduction is performed by which number of scan out of three times scans is added to the synch-block. A buffer 166A outputs successively sample data of audio data included in the sync-block making a sync-block corresponding top a scan number corresponding to the most sync-block out of sync-blocks stored in a memory space corresponding to ECC blocks of two pieces of the SDRAM163 for each channel and for each field as the sync-block to be used. Missing sample data is interpolated by a sample data interpolating circuit 170. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To reproduce correctly a recorded signal even at the time of special reproduction operation and even if making it narrow track pitch is performed.
SOLUTION: For example, two reproducing heads 50-1, 50-2 are provided in the direction of track width deviating their positions for one track. The reproducing heads 50-1, 50-2 are driven by a drive part 80 in the direction of track width in accordance with off-track quantity for a target track. A signal selector 73 discriminates a reproducing head of which the trace state of the target track is appropriate based on error correction results of C1 corrector 62-1, 62-2 and an output level of the reproducing heads 50-1, 50-2, and supplies a signal obtained the discriminated reproducing heads to a C2 corrector 70 and generates an output signal. off-track margin is widened more than the case in which a target track is traced by one reproducing head, a recorded signal can be reproduced correctly even at the time of special reproduction operation and even if making it narrow track pitch is performed.

摘要： PROBLEM TO BE SOLVED: To shorten a time from input of input data to start of recording of the input data. SOLUTION: For example, an ECC block using product codes of 36 pieces is recorded in a 12 tracks with 3 scans. First sync-blocks in which C1 parity is added to a data stream of video data constituting an inner code operation data group are recorded successively. After recoding of the first sync-block is finished, second sync-blocks in which C1 parity is added to a data stream of C2 parity constituting the inner code operation data group are recorded successively. Recording is performed by getting together the C2 parity afterward, calculation may be finished until the C2 parity is recorded. Therefore, before one field being one group of video data to be recorded in 12 tracks all are taken in an ECC encoder, recording of the video data can be started to record.
