Recording and reproduction method and apparatus

摘要

In a recording and reproduction method for recording digital data on magnetic tape by a helical scanning method or for reproducing digital data recorded on magnetic tape by the helical scanning method, a plurality of sectors are generated in each track on the magnetic tape and various types of data, such as video data and audio data, and track-synchronization data are recorded. Pilot signals for tracking control are recorded on the various types of data in a superposition manner by the use of three different frequencies such that the frequency changes every track in a predetermined repetition manner. The pilot signal is recorded so as to have a higher level at least in two blocks in a sector where the track-synchronization data is recorded than in the other portion of each track.
