Abstract: PURPOSE:To measure the head position to a tape with high precision by providing an auxiliary head at a prescribed position of a multi-track recording head device as well as a pair of heads to a multi-track reproducing head device. CONSTITUTION:When the positions of a recording head device 1 and a reproducing head device 2 are controlled to a tape 10, a rough control is carried out so as to shift both devices 1 and 2 to their prescribed positions in the width direction of the tape 10. Then the tape 10 is driven toward an arrow (a), and at the same time a prescribed reference signal is supplied to an auxiliary head 4. Thus an auxiliary track 11 is formed on the side A of the tape 10. This track 11 is reproduced by an auxiliary head 61 with an equal level of reproduction secured between heads 611 and 612. In other words, the device 2 is controlled in the width direction of the tape 10 to secure an equal width of reproduction to the track 11 between the heads 611 and 612.

Abstract: PURPOSE:To simplify the circuit, by supplying AC and DC bias currents to the bias winding of magnetic heads and connecting switching elements in parallel to signal windings and connecting these switching elements to a current source and inputting a digital signal to switching elements. CONSTITUTION:An AC power source Sa and a DC power source Sd are connected to a bias winding lB of magnetic heads MK, and AC and DC bias currents are flowed to this bias winding. Switching elements SWK are connected in parallel to signal windings lK, and they are connected to a current source S. An MOS FET or a bipolar TR is used to input the digital signal to elements SWK. The deflected residual magnetism which is generated on a tape by the unidirectional current source S adjusts the DC bias current and disappeas. Thus, the circuit is simplified, and the multichannel system is realized easily with a pair of power sources.

Abstract: PURPOSE:To ensure an assured prevention for the howling by installing two coils wound round cores each orthogonally and then flowing the high-frequency current to these coils intermittently and with a time shift to secure the radiation of the induction magnetic flux as well as to obtain the reception output. CONSTITUTION:For inductive transmitter 1, coil 3A wound round core 2A and coil 3B wound round core 2B are installed orthogonally to each other, and then the high-frequency current intermittent and with a time shift to each other is flown to the both coils to secure the radiation of the induction magnetic flux. While inductive receiver 11 features coil 13 wound round core 12. And when transmitter 1 comes close to receiver 11 in a certain range, the reception output is obtained regardless of the angular relation between the transmission and reception coils. As a result, the howling can be prevented in an assured way.

Abstract: PURPOSE:To obtain with high yield a magnetic head which excels in the sealing effect by putting an integrated circuit and a multi-element magnetic head on a resin mold material which is previously formed with use of leads to bond them together and casting the resin into a space formed by butting the mold material to a casting mold and then hardening the resin. CONSTITUTION:Wall parts 35a-35c and a bank part 33 are provided to form an integrated circuit storing recess part 32 and a multi-element magnetic head setting part 34, and a resin casting cut part 36 is formed to the side wall 35b at one side of the part 32 to obtain a mold material 31. This material 31 is molded by burying a lead frame 21 which is previously produced with addition of a lead part 23 and an integrated circuit attaching part 22. Then a magnetic head 1, an integrated circuit 41 and a circuit parts 80 are set and bonded to the part 23. A casting mold 61 is butted to the material 31, and the resin is cast through the cut part 36 and hardened. Then each multi-element magnetic head device is removed, and a contact surface between the head 1 and a magnetic recording medium is formed. Thus it is possible to produce with high yield a multi-element magnetic head which excels in the sealing effect such as humidity resistance, etc. with no disconnection of the part 23.

Abstract: PURPOSE:To simplify the circuit constitution of an equalizer and to perform the waveform equalizing processing with high quality by equalizing the waveform by the equalizer after suppressing the low band peak of a reproduced signal through a low band suppressing circuit. CONSTITUTION:A reproduce digital signal is applied to a low band suppressing circuit 23 for suppression of its low band peak. The output of the circuit 23 is applied to an equalizer 24 for equalization of waveform. The output of the equalizer 24 is applied to a digital data detecting/demodulating circuit 18 through a low band compensating circuit 25. The circuit 25 restores the low band component suppressed by the circuit 23 to obtain a correct equalized waveform which is free from the code interference and has the characteristics opposite to those of the circuit 23. Thus the dynamic range is reduced for the signals treated by the equalizer 24. This can simplify the circuit constitution of the equalizer and also perform the waveform equalizing processing with high quality.
