IPC: G11B15/467
Filed: 1991-03-15
Abstract: PURPOSE:To rapidly control tracking by switching the operating state of a tracking control means in accordance with the existence or not of information recorded in a recording medium. CONSTITUTION:An RF signal recorded in a magnetic tape 4 is reproduced by a reproducing head 2. An ATF error signal is detected from a pilot signal included in the reproduced RF signal by an ATF circuit 7. On the other hand, a recorded part or an unrecorded part is judged in accordance with the existence or not of the reproduced RF signal while reproducing by an envelope detector 11. As the result of the discrimination, when the reproducing head is on the recording part, a selector 13 is turned to an ATF bias memory 8 side, a bias value obtained by an operation is added to the ATF error signal and an ATF control signal is obtained. When the unrecorded part is reproduced, the selector 13 is turned to an ATF bias initial value memory 12 side and the ATF control signal is obtained by adding the initial value to the ATF signal.

Title: Automatic gain control circuit
Inventor: AIISO ATSUSHI
IPC: H03G3/30
Filed: 1987-03-06
Abstract: PURPOSE:To prevent the production of an excess amplification output at an input of a large amplitude signal by applying the automatic gain control (AGC) to a main signal path amplifying an input signal at a variable gain amplifier after retarding it by means of a control voltage generated from the input signal before the delay. CONSTITUTION:Part of circuits 4-6 generating an AGC voltage from an output of a variable gain amplifier 2 is used to generate the AGC voltage and a main signal path limiting the amplitude of the audio signal is provided separately. This consists of a circuit 7 retarding the input audio signal and the variable gain amplifier 8 amplifying its output. Then, the gain of the variable gain amplifier 8 is controlled by the same AGC voltage. Thus, the delay in the response of the AGC voltage obtained by the circuits 4-6 is absorbed by the delay time of the delay circuit 7. Thus, the output amplitude is kept constant even at the input of the audio signal at a large amplitude.
