Title: Magnetic disk device
Inventor: TANAKA TOSHIO
IPC: G11B5/00
Filed: 1990-03-12
Abstract: PURPOSE:To cool a magneto-resistance effect type magnetic head with the cooling flow generated by rotation of a disk and to obtain the reproduced output voltage higher than the reproduced output voltage of an ordinary coil type head by using the above-mentioned head for the playback head of the magnetic disk device and supplying a current to the head when the disk attains a prescribed rotating speed which is predetermined. CONSTITUTION:The rotating speed of a driving motor 22a is detected by a Hall element 22b and the rotating speed of the magnetic disk 25 is detected by a constant speed detecting circuit 23 when the disk 25 is rotated by the motor 22a. A command is emitted to a sense current supply circuit 24 to supply the sense current to the magnetic head 21 when the rotating speed of the disk 25 attains a stationary speed. The head 21 is floated by the air flow generated by the stationary rotation of the disk 25 at all times and the head 21 is simultaneously cooled when the current is supplied to the head 21 in such a manner. The temp. rise by the Joule heat generated by the sense current is, therefore, decreased and the flow of the sense current to fuse the head 21 in the absence of wind is obviated.

Title: Rotary head device
Inventor: MATSUMOTO SATOSHI
IPC: G11B5/592
Filed: 1988-03-11
Abstract: PURPOSE:To automatically execute tracking and to enhance trailing performance for the bend of a recording track by fitting a magnetic head on a piezoelectric element plate, and directly driving it. CONSTITUTION:When a prescribed voltage is impressed to a head supporting plate 3 consisting of piezoelectric elements, sagging is generated at an idle edge part farther than the boundary of a supporting stand 5 by a piezoelectric action. At such a time, since a magnetic head 2 attached at the tip part of the head supporting plate 3 also vertically swings, by using a phenomenon, and driving the head in a track width direction recorded on a magnetic tape, the voltage to be impressed is controlled, and the tracking is automatically executed. At such time, since the head supporting plate sags in an A and C directions of arrows, the magnetic head 2 is driven in the range of approximately the same distance with respect to a magnetic tape surface. Consequently, since the distance between the magnetic head 2 and the magnetic tape is constant even during the automatic tracking, a spacing loss at the time of reproduction is not generated, and an excellent regenerative signal can be obtained.

Filed: 1990-03-09
Abstract: PURPOSE:To obtain a result which is approximated to a visual judgement result by processing a picked-up image of a surface to be evaluated and then deciding the extent of contamination. CONSTITUTION:In a graph where an actual wall surface and a photographic material are compared as scale values, scale values are on a straight line which is at 45 deg. to the horizontal in terms of the values of the actual wall surface and a photographic sample and functional inspection is performed to obtain data similar to the wall surface with the photographic sample. When a set of lightness values is divided into two groups based upon a threshold value Lt in the lightness distribution of all picture elements which are inputted to an image analyzing device, the value Lt is so deter mined as to obtain the largest separation between the two groups. Namely, variance sigmaT between the group is omegaS (Ls-La)<2>+omegab(Lb-La)<2>, where omegas and omegab, and Ls and Lb are the picture element ratios and mean brightness values of the low-brightness value group (contaminated part) and high-brightness value group (noncontaminated part) and La is the means brightness of the entirety. The sections of the low brightness value group and high brightness value group are determined with the Lt value which maximizes the found variance.
