Abstract

PURPOSE:To prevent a noise from entering a micro-signal, and also to elevate the SN ratio, by connecting an amplifying circuit consisting of an integrated circuit, to the same substrate that a reproducing coil is connected to. CONSTITUTION:This head is provided with a main magnetic pole 8 and an auxiliary magnetic pole 9, the auxiliary magnetic pole 9 is provided with a recording coil 10 and a reproducing coil 10, and to the reproducing coil 11, an amplifying circuit 12 consisting of an integrated circuit is connected. A variation of a magnetic flux due to magnetization, which is recorded in vertical magnetized film 13 is converted to a curent by the reproducing coil 11, and is amplified to necessary voltage or current by the amplifying circuit 12. According to this constitution, when the reproducing coil 11 and the amplifying circuit 12 are formed close by, a cable for connecting the reproducing coil and the amplifying circuit becomes unnecessary, the influence which an external noise exerts on a circuit is reduced, an external amplifying circuit becomes unnecessary, and the logical processing is simplified.
