摘要： In a system for recording and reproducing digital signals on a magnetic tape by using a rotary head, in which signals are recorded as a series of slanted tracks without guard bands, a pilot signal that controls tracking alignment of a playback head is recorded at a particular position in a specific pilot signal record region, independent from the information signal record region. The pilot signal is arranged at first predetermined positions separated from the ends of the slanted tracks in the pilot signal record region on every other one of the slanted tracks and at second predetermined positions separated from the ends of the slanted tracks in the pilot signal record region on the alternate ones of the slanted tracks. An erase signal can also be recorded in the pilot signal record region such that a start position of the erase signal corresponds substantially to a center portion of the pilot signal on the adjacent track. When the recorded tracks are reproduced by a rotary playback head having a tracing width greater than the track width, the pilot signals from the adjacent tracks will be detected and compared in level, and the comparison output used to control the tracking alignment of the rotary playback head.

摘要： In a system for recording and reproducing digital signals on a magnetic tape using a rotary head, in which the signals are recorded as a series of slanted tracks without guard bands, pilot signals that control tracking alignment of a playback head are recorded at particular positions in a specific pilot signal record region, independent of the information signal record region. Position detecting signals having various recording lengths are also recorded in the pilot signal region in such a manner that the start position of each position detecting signal corresponds substantially to the center portion of the pilot signal on an adjacent track. When the recorded tracks are reproduced by a rotary playback head having a tracing width greater than the track width, the pilot signals from the two tracks adjacent to the reproduced track on either side thereof are sampled by sampling pulses generated in response to the reproduced position detecting signal and compared in level, and the comparison output is used to control the tracking alignment of the rotary playback head.

摘要： In a tracking control apparatus for controlling tracking alignment of a rotary head with respect to record tracks appearing in succession on a record medium and in each of which there are recorded, at predetermined positions varying from track to track in accordance with a predetermined repeating sequence, pilot signals for controlling tracking and position detecting signals having different recorded length and which identify the positions of the pilot signals. An identifying signal for identifying the recorded length of a position detecting signal recorded in a track being traced by the rotary head is generated from the output of the rotary head, and a sampling signal is generated in response to the identifying signal for sampling a pilot signal reproduced as cross-talk from an adjacent track so as to reduce the pull-in time of the tracking alignment operation.

摘要： In a system for recording and reproducing digital signals on a magnetic tape using a rotary head, in which the signals are recorded as a series of slanted tracks without guard bands between adjacent slanted tracks, a pilot signal that was recorded during the recording process is used to control the tracking of the playback head. The pilot signal is recorded at a specific position in a specific pilot signal record region, independent from the region of the track at which the informational signal is recorded and the pilot signal is arranged at a predetermined position or positions being a specified distance from an end of each track in its longitudinal direction and only alternate tracks receive such pilot signal. When the recorded tracks are reproduced by a rotary playback head having a tracing width that is greater than the width of the track, the pilot signals from the adjacent tracks will be detected and can be compared in level, with the comparison output being used to control the tracking of the rotary playback head.

摘要： A rotary head apparatus of the type which reproduces digital signals recorded in one or more oblique tracks on a recording medium, the digital signals being formatted such that one frame of the digital signals is formed of n blocks, each block having added to it a block address and a frame address, wherein the apparatus compares the frame address from the reproduced signal with a reference frame address which varies with a reference period, and the transporting speed of the recording medium is then controlled so as to make the difference between the reproduced frame address and the reference frame address constant.
