Title: Magnetic recording and reproducing device
Inventor: HOSHIYA HIROYUKI
IPC: G11B5/31
Filed: 1995-06-12
Abstract: PURPOSE: To prevent the output from lowering due to a current leakage and the insulation from deteriorating by making a material for constituting a magnetic shield and a flux guide extremely high in electric resistance. CONSTITUTION: One end part of a magneto-resistance effect laminated film 10 is exposed on an opposite surface 37, while the other end part is in contact with the flux guide 11. When an opposite surface 67 to the flux guide 11 and an end part on the other side are magnetically and electrically short-circuited with magnetic shields 81 and 82, magnetic path resistance of a magnetic circuit formed along the heightwise direction 62 of the element can be lowered. When a vertical bias film 37 is disposed in contiguity to end parts of the magneto- resistance effect film 10 and the flux guide 11 in the track widthwise direction 61, magnetic domain control can be performed on the magneto-resistance film 10 and the flux guide 11, and hence noise is suppressed.  The vertical bias film 37 consists of a film having a residual magnetization component parallel with the track width direction 61 by using, for instance, a cobalt-platinum film as a high coercive force material, but some other hard magnetic thin film or a magnetic film of exchanged connection with anti-ferromagnetic substance is also capable of obtaining the same function.

Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To obtain an adjusting device which prevents a read defect, a write defect and the like due to a sudden change in an ambient environment and in a usage frequency by a method wherein a temperature in a specific part inside an apparatus is measured by a measuring device, the distance between a head and a pilot roller is changed so as to correspond to the measured temperature and the gap between both is ensured properly. SOLUTION: A CPU 50 measures the temperature of a pilot roller 18 inside an apparatus by using a non-contact thermometer 20, a gap is read out by a table on the basis of the temperature, and a head movement amount corresponding to the difference between a gap value and the temperature is computed. On the basis of the movement amount, the speed of rotation of a reversible motor 23 is found, the motor 23 is driven via a motor driver, the motor 23 is rotated until the measured value of an encoder 27 reaches the speed of rotation, a magnetic head 17 is moved up and down via a pinion mechanism, and the gap between the head 17 and the piloy roller 18 is adjusted to an optimum value. When this treatment is repeated, the gap can be adjusted always to the optimum value irrespective of a temperature change.

Title: Variable attenuating circuit
Inventor: SANO SHINYA
IPC: H03G3/02
Filed: 1982-08-20
Abstract: PURPOSE:To prevent spike noises caused by the ON/OFF operations of a switch, by connecting a capacitor between an output terminal at the hot side of an integration circuit and the feedback resistance joint of an inverse input terminal of an external operational amplifier. CONSTITUTION:A capacitor 8 is put between an output terminal 3 at the hot side of an integration circuit 1 and the feedback resistance joint of an inverse input terminal of an operational amplifier. Then a leak resistance 9 is connected between the terminal 3 and an output terminal 4 of the earth side in order to supply the DC potential to the circuit 1 of the capacitor 8 when switches S1-S7 are set at the earth side. As a result, no change is caused in the resistance value of the inverse phase input circuit of the amplifier 5 by the function of the capacitor 8 even in case the resistance value varies by operations of switches S1-S7 when the IC side is viewed from the side of the terminal 3. Thus the spike noise is never generated.

Title: Magnetic recording and reproducing device
Inventor: IDEI TOSHIO
IPC: G11B5/588
Filed: 1983-08-08
Abstract: PURPOSE:To attain the satisfactory tracking control with a simple circuit by obtaining the difference frequency component between a pilot signal of a video track and that of an adjacent track to said video track by the cross modulation of the pilot signal which is produced at a repeatedly recorded area of the video track. CONSTITUTION:A control pilot signal is recorded on video tracks 31-35 as overlapped on a video signal by a recording head 36 having the width larger than the track pitch. The recording is carried out repeatedly at the areas 37-39 shown by oblique lines. A reproduced signal supplied to an input terminal 41 is applied to a BPF24 and a BPF25 and converted into the DC voltage by amplitude detectors 26 and 27 respectively. An output difference is calculated by a subtractor 28 and fed back to s tracking servo means 29. Thus the tracking is performed by the difference frequency obtained by the cross modulation of the repeatedly recorded part between two adjacent tracks. Therefore the coincidence is obtained between the center lines of the loci of a recording head and a reproducing head. Thus it is possible to perform the joint shooting and the partial rerecording to a recorded track without exercising any special tracking control.
