Abstract: A thin film formation method in accordance with the present invention forms banks (110) where affinity bank layers and non-affinity bank layers are alternately layered by repeating a step of forming an affinity bank layer (111-11n) with a material having affinity for a thin film material solution (130) (such inorganic material as SiO2) and a step of forming a non-affinity bank layer (121-12n) with a material having non-affinity for the thin film material solution (130) (such organic material as resist) one or more times. Finally the thin film material solution (130) is filled between banks by an ink jet method, heat treatment is executed, and a thin film layer (131-13n) is sequentially layered. By these steps, cost required for affinity control can be decreased and forming multi-layer thin films with uniform film thickness becomes possible.

Abstract: A voltage-mode boosting write driver circuit (40) having a pair of voltage boosting PMOS transistor sets (44, 46) coupled to a high current H-switch (42). One set (44) of the boosting PMOS transistors correspondingly pulls output pin HY high, while the other transistor set (46) correspondingly pulls output pin HX high and the other output pin HY low thereby significantly improving the head voltage swing, and also achieving a faster slew rate.

Moreover, less power dissipation and smaller number of devices used are achieved by making use of existing transient currents of the pre-driver emitter follower stage.

Abstract: The position error signal (PES), representing relative position regarding position information (RRO) previously recorded on a magnetic disk and the magnetic head, is averaged in each servo sector by an averaging unit, and a control input is obtained based on the PES by a phase compensator and the control input undergoes an averaging process in each servo sector by another averaging unit. Convolution integration with respect to the signal data processed by those averaging units is carried out by using a transfer characteristic formed by adding 1 to an open-loop transfer characteristic, which is determined by a magnetic head actuator model and a servo control circuit, to obtain a synchronous vibration estimate. This estimate undergoes a high-pass filtering process of a zero phase error characteristic by the filter unit to remove the vibration component of low frequency band and to thereby obtain a synchronous vibration learned value with high precision.

Abstract: A thin-film magnetic head has a second lower core layer sandwiched between a magnetic pole laminate, which is formed of a lower magnetic pole layer, a gap layer, and an upper magnetic pole layer laminated in this order from bottom to top, and a first lower core layer. Unlike a conventional thin-film magnetic head, this thin-film magnetic head does not include a gap depth defining layer. This arrangement makes it possible to easily form the magnetic pole laminate into a substantially rectangular shape, and solves the problems with the conventional thin-film magnetic head attributable to the presence of the gap depth defining layer, the problems being typically represented by a curved gap layer or a reduced volume of the upper magnetic pole layer. Thus, the intensity of a recording magnetic field in the vicinity of a gap can be stabilized and increased, allowing the manufacture of thin-film magnetic heads capable of successfully achieving narrower tracks.
