摘要： PURPOSE:To reduce effectively the fluctuation of a floating amount due to a change of a Yaw Angle by extending both end sections of a cross rail between both side rails to an air flow-out side along said side rails with a space without connecting with the respective side rails. CONSTITUTION:Both end sections of a cross rail 3 between both side rails 1 for generating a positive pressure are extended at an air flow-out side along both side rails 1 with a space without connecting with the respective side rails. Between two extending end sections 23a and 23b of the cross rail 3, a negative generating section 4 is formed. Namely, Both the side rails 1 for generating the positive pressure and the negative pressure generating section 4 formed between the two extended end sections 23a and 23b by extending both the end sections of the cross rail 3 to the air flow-out side along the respective side rails 1 are respectively separated by groves 21a, 21b.

摘要： PURPOSE:To prevent attraction of a magnetic head slider by changing the thickness of a magnetic disk medium in radial direction, simultaneously setting the height of mounting to make the load to a floated slider positive in a thick area and negative in a thin area when the negative pressure type slider is seeked in the radial direction. CONSTITUTION:When the negative pressure type magnetic head slider 2 is placed at the position A of seek starting of a magnetic disk medium 1 at the time of starting and stopping, the magnetic disk medium 2 is kept still at the height ha even when it is driven and rotated. In loading, when the slider 2 is moved to a position B after starting and rotating the magnetic disk medium 1, it is floated by very small height. Then, when the slider 2 is seeked in the direction of the position A, it keeps floating at the prescribed height. Accordingly, the amount of floating does not change due to a hysteresis phenomenon. In stopping, when the magnetic medium 1 is stopped after shifting the floating slider 2 to the position A, the slider 2 is unloaded and kept at the position A at the supported height ha.

摘要： PURPOSE: To etch a substrate down to a desired depth with good accuracy by using a metal mask for ion etching having the double layered construction consisting of a metallic film for controlling the rate of etching in the substrate and a thin metallic film for detecting the end point of etching.
CONSTITUTION: The 1st thin metallic film 2 (for example, copper of about 500W1,000Å) for detecting the end point of etching is vapor-deposited on a substrate 1. The 2nd metallic film 3 (for example, Ti) of a desired thickness (t) to be used as a monitor mask is deposited by evaporation on the film 2. A resist mask film 4 is then selectively formed thereon and with said film as a mask, the film 3 and the film 2 are selectively etched by an anisotropic plasma etching to expose the prescribed region 5 of the substrate 1. The film 4 is further removed by a plasma ashing method and the region 5 of the substrate 1 is etched simultaneously with the film 3 by ion etching with the film 3 as a monitor mask to etch the region 5 down to a prescribed depth D and thereafter the film 2 is removed.

摘要： PURPOSE:To use a disk in a high-speed rotating state and to use even the disk surface on where no stabilizing plate is present, by providing a magnetic head device on the opposite side to the stabilizing plate with a flexible disk between. CONSTITUTION:When the flexible disk 1 is pressed toward the stabilizing plate 2 by the magnetic head 3, these is a range where repulsive force increases in proportion to the extent of displacement of the disk. The range of the displacement extent which causes said condition, through varies with the rotating speed of the disk, attains hundreds mum at relatively high speed rotation. Therefore, the magnetic head is pressed against the flexible disk from the side where no stabilizing plate is present to hold the head in excellent contact by the repulsive force produced in the desk unless the disk is deformed beyond said range.
