摘要： A signal which is to be used in high-speed playback is recorded in a predetermined region of a track. An error correcting check code region for recording an error correcting check code is formed at a position adjacent to the predetermined region. In accordance with the usage, an error correcting check code for high-speed playback, an error correcting check code for normal playback, or predetermined fixed data is recorded in the error correcting check code region. In a digital VTR which records and plays back data at plural kinds of data rates, trick playback data are recorded so that a head scans a subcode area or a VAUX area in high-speed playback at a predetermined tape running speed in each record mode. An area for recording an error correcting check code is used as an area for, in addition to an error correcting check code for normal playback, recording an error correcting check code for trick playback, normal playback data, or trick playback data.

摘要： During retrieval of data from tape in a helical scan tape drive mechanism with a rotary head drum, movement of tape past the drum by a capstan is controlled to keep the tracks recorded on the tape in alignment with paths followed by the heads. A time interval is measured between occurrence of a drum position pulse generated at a specific angular position of the drum, and detection of reference signals included in the tracks (such as specific portions, with known bit patterns, of the data in the tracks). The capstan is operated to keep this interval equal to a set reference value. If a change in the reference value is required, such as at a transition between data recordings made at different times, the tape is moved at a slower than normal speed, and multiple measurements are made of the time interval as it cycles through a range of values in consequence of the changed tape speed. The mean value of these multiple measurements is used as the new reference value.

摘要： When a transport packet of the MPEG2 signal is recorded, a tape speed is reduced to 1/2 or 1/4 of that used to record standard data in accordance with the bit rate of the program. Two heads (A and B) having different azimuths are provided in close proximity with each other at the same height on a drum. If the 1/2 tape speed mode is selected, the recording is performed by head A during the first scan of the tape and by head B during the next scan. Even when the tape speed is a fraction of an even number of the standard tape speed, the azimuth angles of adjacent tracks are different and azimuth recording is performed to reduce crosstalk.

摘要： It is known in the case of digital helical track recording and replay apparatuses for audio, video and general data to be recorded for pilot tones to be interleaved in the data tracks, for tracking. The interleaving can be carried out simultaneously with the data by frequency decoupling (a) or by superimposition (b). The invention is based on the object of providing a helical track recording and replay system which carries out tracking in a simple manner. According to the invention, the ATF signal is obtained in a filter module, which also carries out the rectification of the filtered-out pilot tones. The two DC voltage levels are interrogated and processed in the servo microcontroller, with A/D converters. Coupled to the rotation of the head drum, pulses are produced by the servo system which switch the ATF conditioning over between direct operation and tracking operation, so that evaluation is achieved by the microcontroller during the fast ATF burst phase.

摘要： A tracking control apparatus for a tape-shaped recording medium according to this invention is operative, prior to carrying out actual reproduction, to measure times from the time point serving as reference phase position within one period of the rotary drum to the time points when timing signals of respective recording areas of the tape-shaped recording medium are detected by the head, and to calculate average values every respective recording areas of the measured times to generate reference value on the basis of the maximum value and the minimum value of the calculated average values of the respective recording areas. Further, in actual reproduction, times from the time point serving as reference phase position to the time points when the timing signals of the tape-shaped recording medium are detected by the head are measured to control relative velocity between traveling velocity of the tape-shaped recording medium and rotational velocity of the rotary drum on the basis of result of comparison between the measured times and the reference value. Thus, even in the case where particularly the relationship between the scanning locus of the reproduction head and the track shape is not ideal, satisfactory tracking can be carried out over the entire area of the track. As a result, reliability of, e.g., digital data storage using such tracking control apparatus for tape-shaped recording medium can be improved.

摘要： A digital VTR is capable of reproducing a recorded picture image in a normal mode and a variable speed reproduction mode. During normal speed reproduction, the digital VTR reproduces a recorded picture from data that has been recorded in a normal play area of a recording medium. When the digital VTR is in a variable low speed reproduction mode, it reproduces a picture from data recorded in a first trick play area. When the digital VTR is in a variable high speed reproduction mode, it reproduces a picture from data recorded in a second trick play area. The first and second trick play areas are located at respective tracks that correspond to different azimuths.
