Magnetic recording/reproducing apparatus using segment recording system |
摘要 |
A digital VTR using Automatic Track Finding (ATF) of a four frequency pilot signal system, employing a multiple segment recording system for high density recording and wide band recording. In a recording mode, a segment code signal is recorded on each track in response to a frame synchronizing signal. In a reproduction mode, the phase difference between the reproduced segment code signal and the frame synchronizing signal is detected by phase comparing circuit 26. The rotation speed of capstan motor 29 is controlled so that the phase relation of one signal in the reproduction mode becomes the same as that in the recording mode. As a result, it is possible to reproduce a stable video in the VTR using the segment recording system.
