摘要： PURPOSE: To provide a magnetic head slider, the floating characteristic of which is hardly affected by the working tolerance of tapered parts. CONSTITUTION: The magnetic head slider which is provided with a main body 2 of the slider, at least two rails 12, 14 for generating the floating force, and a magnetic head part 10 for recording/reproducing data, is constituted in such a manner that ends of the tapered parts 12T, 14T of rails are positioned at each of positions where the rail widths are decreased. Consequently, the floating characteristic is hardly affected by the work variation of curved surface parts.

摘要： PURPOSE:To easily realize a magnetic head slider of high reliability by inclining an air inflow part to so that it does not contribute to generation of a floating force. CONSTITUTION:Air inflow parts to plane parts 17a, 17b of floating rail parts 12, 13 on the air outflow side of floating rails 12, 13 which have slope parts 14, 15 and two plane parts 16a, 16b and two plane parts 17a, 17b separated by notched grooves 18, 19 are inclined at 5 to 60 deg. so that they do not contribute generation of a floating force. since edge parts E1 where inclined parts 20a, 10b and plane parts 17a, 17b are brought into contact with each other in air inflow parts are made gentle, shaving of minute projections on the magnetic disk surface to damage the disk is considerably reduced at the time of CSS operation to prevent head crush.

摘要： PURPOSE:To remove the dust stuck to the head and to prevent the shifting to the CSS zone of the disk by placing temporarily the head in the non- contacting condition on the non-recorded zone of the position approximate to the contact start stop (CSS) zone of the disk surface in the stopping initial period. CONSTITUTION:When a motor control signal Ms to show the disk rotating stopping command is received and a motor driving circuit 14 stops and controls a spindle driving motor 13, the number of revolution of a disk 11 is gradually reduced and a seek signal generating circuit 26 generates the first step seek signal Ss. By the seek signal, a head shifting motor 24 shifts a head 21 onto the non-recorded zone OA approximate to a CSS zone SA. The shifted head 21 reduces the floating quantity based upon the reduction of the number of revolution of the disk 11 and approaches the disk surface greatly. At such a time, a dust 31 stuck to the head surface contacts with the non-recorded zone OA of the disk 11 and shifts, and the head 21 is cleaned. Thereafter, a seek signal generating circuit 26 generates the seek signal Ss of the second step and shifts the head 21 to the CSS zone SA.

摘要： PURPOSE:To load and unload safely a head slider and to improve the reliability of a magnetic disk device by using a simple pressure mechanism to give the temporary displacement to the head slider. CONSTITUTION:In an inactive mode of a magnetic disk device, a magnetic head slider 7 is carried by an actuator 12 and set on the home position 9 of a magnetic disk 10. A support spring 3 is set free since a projection 5 of the spring 4 has no contact with a pressure guide 6 provided at the side of the disk device. The slider 7 is separated from the disk 10 by the action of the spring 4. When the disk device starts its action, a carriage 3 moves toward an arrow head B and the slider 7 reaches the boundary between the position 9 and a track area 8. Then the projection 5 is pressed toward arrow heads C and C' by the guide 6. Thus the slider 7 moves close to the disk 10. Then the slider 7 is set on the area 8 in an action mode, and a gap is set automatically by a self-control function for floating amount of the slider 7.

摘要： PURPOSE:To make it possible to use both faces of a floppy disc by providing a stabilizing plate for each of both recording faces of the floppy disc and providing switching means which can shift the floppy disc so that the floppy disc is foated above the surface of one stabilizing plate and is rotated and providing a magnetic head which can write and read information onto and from the floppy disc. CONSTITUTION:When a floppy disc 2 starts rotating by a spindle 1, and the disc 2 is attracted to one of stabilizing plates 3 and 4 in accordance with rotation conditions, but the disc 2 is attracted to the stabilizing plate 4 initially. If the disc 2 should be shifted to the stabilizing plate 3, switching pins 8 and 7 are taken out and in; and when the disc 2 is floated above the stabilizing plate 3 and is rotated, data is written onto or read from the disc 2 by a magnetic head 5. If the right recording face should be accessed after accessing the left recording face, pins 7 and 8 are taken out and in to shift the disc 2 to the stabilizing plate 4 by the pin 7, and data is written or read by a magnetic head 6.

摘要： PURPOSE:To prevent the damage of a magnetic disc, by depressing a slider with a force more than a floating force of the slider based on a rotary moment produced at the slider when a carriage crashes into a stopper. CONSTITUTION:The moment when a carriage runs away right as shown in Figure and crashes into a stopper, a force malpha is exerted to a center of gravity A of a slider 1 (where; m is the mass of a slider 1 and alpha is a speed of the slider 1). A rotating moment M is exerted to the slider 1, and taking a distance between the center of gravity A of the slider 1 and a support plane of a cymbals as d, M=malphad is obtained. The revolution of the slider 1 causes a force F to lift up the center of gravity by taking a side B of the tip of the slider as a fulcrum. Taking the width of accessed direction of a bottom plane of the slider as S and the center of gravity as at a distance of S/2 toward right from the side B, F=MX2/S=malphadX2/S is obtained. Thus, damage can be prevented, even if the carriage crashes into the stopper, by applying a depressing force F0 greater than F to the slider 1 with a plate spring 3.

摘要： PURPOSE:To manufacture a horizontal thin-film magnetic head of small magnetic core resistance by forming an upper magnetic layer by working a bolster material arranged previously under a gap part in the manufacture of the magnetic head. CONSTITUTION:On substrate 6, lower magnetic layer 7 is formed and on it, conductor coil 9 is formed with insulating layer 8 interposed. Further, bolster material 10 is provided on it, upper magnetic layer 13 with gap 12 is formed with insulating layer 11 interposed, and the projecting part (the upper part of bolster material 10) of magnetic layer 13 is worked by lapping to reduce its thickness. Therefore, since the above-mentioned head has the magnetic layer thinned near the gap part. The leakage of magnetic flux of the gap part lessens and the overall magnetic resistance of the core decreases.
