Title: Magnetic head slider
Inventor: KAWASAKI GOROU
IPC: G11B5/60
Filed: 1993-12-07
Abstract: PURPOSE:To stabilize a floating amount by forming an inclined surface to have an inclining angle of not larger than a specified angle and a length in a direction of an air flow of not smaller than a specified mum, and making a decrease of the floating amount as small as negligible even when dusts adhere to the surface. CONSTITUTION:A magnetic disc 44 set to a spindle 43 is rotated when a spindle motor 42 starts moving. As the air enters a magnetic head slider 30 at this time, a negative pressure to attract the magnetic head slider 30 to the magnetic disc 44 is generated at floating surface of rails 21, 22, 23. In consequence, the slider 30 floats and stops at a height where the forces in both directions balance with each other. Corners 21b, 22b, 23b at front edges of the rails 21, 22, 23 from which the air enters are notched large to reduce straight parts at the entrance ends, and also inclined surfaces 21a...23a are formed. Consequently, dusts are hard to adhere to the floating surfaces of the rails 21...23. A floating amount of dusts can be reduced by setting an inclining angle of each inclined surface 21a...23a to be not smaller than 3 deg., and a length in a direction of the air flow to be not smaller than 50mum.

Title: Magnetic head
Inventor: KAWANO KANJI
IPC: G11B5/31
Filed: 1987-12-07
Abstract: PURPOSE:To enable stable tape traveling in spite of long-period traveling and to obtain good head characteristics by rounding the sliding surface of a head and rounding the step part in the notch of the head by executing rounding to the equal radius.

Title: Low-frequency amplifier circuit
Inventor: TAKADA YUJI
IPC: G01J1/44
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To obtain the same gain and frequency characteristics as before without using any electrolytic capacitor even when a small capacity value that can be obtained by ceramic or a film capacitor is used by connecting a capacitor between a 2nd differential input terminal of a 2nd operational amplifier and a constant-potential point. SOLUTION: A 1st operational amplifier IC1 imposes low-frequency amplification on an input signal applied to an input terminal and outputs the resulting signal to an output terminal. The 2nd operational amplifier IC2 appears to amplify a capacitor C1 connected to the uninverted input terminal. Denoting as C0 the equivalent capacity obtained by viewing the output of the 2nd operational amplifier IC2 from the inverted input terminal ('A' point) of the 1st operational amplifier IC1, C0=C1×R2/R1 holds. Further, the DC impedance viewed from the 'A' point becomes equal to R1 since the output impedance of the operational amplifier IC2 is extremely small. Consequently, the same gain and cutoff frequency as before can be obtained.
