  • Adjustment Of The Magnetic Head Position Track Following On Tapes (AREA)

Abstract

PURPOSE: To perform excellent high density recording and accurate tracking operation, by tracking control of magnetic head based on the reference signal at recording and reproduction.
CONSTITUTION: The magnetic disc D is driven and turned in the turning period which is a integer multiple of the TV signal one field period with the drive motor M, further the magnetic head MH having recording and reproduction function is in synchronizing with the turning period with the head carrying set and it is continuously moved in a given speed radially to the disc D, and at recording mode, the recording trace in spiral shape by the information signal is formed on the disc D with the head MH, and at playback mode, the same trace as the spiral recording trace can be formed. In performing recording through the use of the disc D, the reference signal recorded already is reproduced and given to the tracking control system, and the head MH traces the intermediate place of the two adjacent recording traces with different reference signal under this control and records TV signal. At playback, the reference signal recorded and the horizontal synchronizing signal in FM form are reproduced and they are given to the tracking control system and controlled.
