Magnetic recording and reproducing device
专利汇可以提供Magnetic recording and reproducing device专利检索，专利查询，专利分析的服务。并且PURPOSE:To perform switching of a noise reducing cirucit, etc., and music selection and program searching by the absolute address easily by controllng the combination segmentation of a constant frequency signal through a selecting circuit, etc., and thus forming and recording great numbers of control signals. CONSTITUTION:When the ceasing of a signal by the opening and closing of a gate circuit 2 is detected, a no-signal detecting circuit 3 generates a pulse, and according to the signal from the terminal 1 of a counter 4 for counting said pulse, switching circuits 5 and 6 segments a constant frequency signal from a signal generating source 31 to record the constant frequency signal on either or both of the lift and right channels of a magnetic tape according to the switching of the switches S1 and S2 of a control signal generating circuit 7 for switching. Those three signals are used as selection signals for a noise reducing cirucit and an equalizer circuit. Then, nine kind of signals obtained by using those three kind of control singals in combination on the basis of successive signals outputted from the terminals 2 and 3 of the counter 4 are used as channel control signals which use absolute addresses, thereby easily performing selection of the noise reducing cirucit, etc. and music selection and program searching by the absolute addresses.，下面是Magnetic recording and reproducing device专利的具体信息内容。
