摘要： A magnetic head for reading from and/or writing to a magnetic information storage medium has a substrate on which a plurality of thin films are formed in sequence. The films provide a magnetic circuit having a magnetic gap, a bottom pole piece and a top pole piece overlying said bottom pole piece. The top pole piece is formed as a tip portion adjoining the magnetic gap and a rear portion which makes magnetic contact with the tip portion. The rear portion is formed in the sequence after the tip portion. To ensure accurate thickness and width of the tip portion, a non-magnetic protective film is formed on the tip portion after the tip portion is formed and before the rear portion is formed.

摘要： In a magnetic disk device having a composite head with an induction type of recording head adjacent a magneto-resistance effect type of reproducing head, a read error relief is provided to relieve read errors caused by Barkhausen Noise or Base Line Shift phenomenon inherent to the magneto-resistance effect type of reproducing head. Upon occurrence of a read error, a re-try function is first executed, and a track offset function is executed for relief of the read error. However, if the read error is not relieved after the offset operation and the re-try operation have been performed a predetermined number of times, then a pseudo write-in and/or read current control operation is performed together with the offset operation and/or re-try operation for a predetermined number of times. The control operation varies the magnetic domain structure in the head magnetic film (MR film). The variation of magnetic field and/or read current in the head magnetic film causes the magnetic domain structure of the head magnetic film to be varied, so that the Barkhausen Noise or the Base Line Shift phenomenon are extinguished.

摘要： A method of making a silicon diaphragm pressure sensor includes forming an oxide film on one surface of a monocrystalline silicon substrate. A polycrystalline silicon layer is formed on the oxide film. The oxide film may be partly removed before the formation of the polycrystalline silicon layer. The polycrystalline silicon layer is heated and melt to recrystallize the same, thereby converting the polycrystalline silicon layer into a monocrystalline silicon layer. On the monocrystalline silicon layer may be epitaxially grown an additional monocrystalline silicon layer. By using the oxide film as an etching stopper, a predetermined portion of the substrate is etched over a range from the other surface of the substrate to the oxide film, thereby providing a diaphragm of the pressure sensor.

摘要： A thin film magnetic head which can suppress magnetic saturation at opposite ends of width of a narrow track width to reduce the amount of recording side-fringing onto a recording medium and which can assure a necessary recording magnetic field satisfactorily. Also a magnetic disk apparatus using the head. A second magnetic yoke has a magnetic gap depth over which the spacing of a magnetic gap keeps substantially equal toward a rear portion of the second magnetic yoke, starting at the tip of a second magnetic pole and the spacing between a first magnetic yoke and the second magnetic yoke is increased toward the rear portion, starting at a position corresponding to the magnetic gap depth. The second magnetic pole of the second magnetic yoke has in the track width direction a width for recording a signal on a track width of the recording medium. The width keeps constant over a predetermined length toward the rear portion, starting at the second magnetic pole tip and spreads monotonically toward the rear, starting at a position corresponding to the predetermined length. The predetermined length terminating in the spread start position of the width of the second magnetic yoke is set to be shorter than the magnetic gap depth.
