摘要： PROBLEM TO BE SOLVED: To realize a magnetic disc apparatus with high speed operation, high recording density and high reliability by a method wherein a slider can be turned easily around a shaft parallel with a disc surface, the strength of gimbals is improved and a sufficient bonding strength against a load is provided. SOLUTION: A metal layer 7 is provided on the side of a slider spacer 2 which faces the rear surface of a slider 1 in order to decompose peroxide compound catalyst contained in denatured acrylic system bonding agent 6 by the reductive reaction to activate the catalyst reaction. With this reaction, the slider 1 and the slider spacer 2 are bonded to each other with a sufficient strength by the radical polymerization of the reactive components. With this constitution, a magnetic head supporting mechanism in which the separation of the slider 1 and the breakage of gimbals 3 which are caused by a force in a direction parallel with a disc surface are hardly produced and which has the gimbals 3 with which the slider 1 can be turned around a rolling axis and a pitching axis easily can be obtained. Therefore, as the magnetic head supporting mechanism with which the displacement of the slider in a direction parallel with the disc surface is hardly produced and the slider can be turned easily and which is hardly broken by a load is provided, high speed operation and high speed positioning can be realized, a high recording density can be achieved and high reliability can be realized.

摘要： PROBLEM TO BE SOLVED: To embody a disk device of a high speed and high recording density by decreasing the variations in the flying height by the warpage and twist of gimbals and a slider which occur at the time of assembling a head, thereby suppressing the lower floating of the slider and the change in the flying height at the time of operating. SOLUTION: This mechanism is so constituted that the slider 1 mounted with the magnetic head is fixed by adhesion with an adhesive 3 to the tongue parts 2a of the gimbals. The tongue parts 2a of the gimbals on the side opposite to the surface facing the rear surface 1a of the slider are partly or fully etched, by which the plate thickness t1 is made partially thinner than the thickness to of the other regions and the rigidity of the tongue parts 2a of the gimbals is selectively lowered to the min. required extent. The deformation of the slider floating surface 1b of the slider 1 occurring in the difference in thermal expansion, etc., between the tongue parts 2a of the gimbals and the slider 1 is prevented. The lower floating of the slider 1 and the change in the flying height at the time of operating are thus suppressed.

摘要： PURPOSE: To decrease the variations in the flying height of a slider and positioning errors due to mis-positioning of a head and to increase the speed and capacity of this device by forming a recessed part on the circumference of a fixing part by welding on the side of a slider spacer in contact with gimbals. CONSTITUTION: The adhesive surface side of the slider spacer 2 with the slider 1 by an adhesive 10 is provided with a recess 2a larger than the stationary region 4 and is irradiated with a laser, etc., from the bottom of this recess, by which the spacer 2 is welded to the gimbals 3. Further, the circumference of the recess 2a is provided with a concentrical ring groove 2b around the region 4 to relieve the shrinkage of the spacer 2 by thermal stress on welding and to avert the deformation on the adhesive surface side. Then, the deterioration with lapse of time and the outflow of the adhesive are decreased by welding and fixing and further, the variations in the thickness of the adhesive layer by the deformation of the adhesive surface are decreased. As a result, the flying height of the slider is lowered and the positioning accuracy is improved, by which the speed and capacity of the device are made higher.
