专利汇可以提供Automatic tracking correction system专利检索,专利查询,专利分析的服务。并且PURPOSE:To secure application of the tracking correction signal to the reflectable element by means of the magnetic converting means comprising of the double-gap head which possesses a pair of reproduction gaps functioning independently to each other. CONSTITUTION:The output of correction reproduction gap g2 and main reproduction gap g1 are applied to terminal 12 and 14, and BPF16 makes pass through the FM frequency equivalent to the horizontal syncronization. The output of g1 of terminal 14 is separated for the horizontal synchronization via demodulator 18 and horizontal synchronous separator 20. This separated horizontal synchronization is turned to the trigger signal which switches on switch 22 for the horizontal synchronous period as well as to be the trigger signal which switches on switch 26 via (1H - 2tau')-delay circuit 24. Amplifiers 32 and 34 change the output of peak detection circuits 28 and 30 into the direct current each. The output of amplifier 32 deflects upward bimorph 36 which supports the head; while the output of amplifier 34 deflects downward the output of bimorph 36 respectively.,下面是Automatic tracking correction system专利的具体信息内容。
