Abstract

PURPOSE:To fix the noise band to a prescribed position of the screen stably with a high precision in a short time, by controlling the capstan motor according to the relation between the stop position pulse and the noise position pulse. CONSTITUTION:The signal of approximately 10ms pulse width is used as stop position pulse (a) and is divided into front part P1 of approximately 2ms, middle part P2 of approximately 3ms, and back part P3 of approximately 5ms. When noise position pulse (b) enters to middle part P2, intermittent feeding of the tape is stopped. When noise position pulse (b) enters to front part P1, the capstant motor is driven in a low speed; and when pulse (b) enters to back part P3, the capstan motor is inverted.
