摘要： PURPOSE:To increase gap depth and to obtain a thin film multi-track head having long head life by forming a thin film core between a cone-shaped surface formed on a substrate and a gap material like a wave. CONSTITUTION:Cone-shaped unevenness is formed on one surface of the substrate 1b with track pitches Tp and a magnetic core 2b is formed on the unevenness. If it is defined that the conical angle of the core 2b is 60 deg., each track width is Tw, the gap depth is (gd), core thickness is (t), the cutting depth of the core is (l), the sectional area of the core is Sc, and opposite area of a gap part is Sg, Sc=2.t.l and Sg=Tw.gd are satisfied. In order to display the function of the head sufficiently, Sc>Sg, i.e. l>2/3 .gd becomes the necessary condition. It is required to set up the gap depth (gd) to about 30mum in such kind of head. If Tp=2Tw when the Tw is 100mum, the cutting depth (l) becomes 100mum, so that no trouble is generated even if the gap depth (gd) is 30mum.

摘要： PURPOSE:To attain measurment of the floating characteristics of a slider, an infinitesimal floating amount, the floating amount of a parallel floating slider and the floating amount of a slider having an air bearing part of a complicated form respectively, by attaching a light transmissible plate member to the slider. CONSTITUTION:When light Iphi of a light source is made incident on a slider 2, the incident light Iphi is reflected from the lower sides of glass plates 4a and 4b respectively to produce reflected light I1. At the same time, the light Iphi is reflected from the upper surface side of a disk 5 to produce reflected light I2. Gaps between the disk 5 and aplates 4a and 4b are measured from the interference fringes generated from both beams I1 and I2. While the floating amount (h) of the slider 2 is obtained by measuring the height of the surface sides of a slider air bearing part 3 and the height hsft of plates 4a and 4b and subtracting these heights from each other. Then the floating amount of the slider 2 can be measured from the combination of a real disk and a real slider. While a microminiature floating amount of the slider 2 can be measured by setting the height hsft of the plates 4a and 4b at >=0.2mum.

摘要： PURPOSE:To decrease the oscillating amplitude of a head supporter and to facilitate the stable holding of a magnetic head onto a storage track, by constituting the supporter of the magnetic head of a composite spring material obtained by laminating a metallic spring material and a metallic attenuation material. CONSTITUTION:An air bearing slider 2 containing a magnetic head is attached to a supporter 4 via a flexible matter 3. The supporter 4 is attached to a rigid arm 5 and consists of an elastic part 6 and a load beam part 7. Furthermore the supporter 4 has a lamination structure of three layers, that is, a metallic spring material 8 of SUS304 and metallic attenuation materials 9 and 10 of Cu which are press-fixed to both sides of the material 8. The thickness td1 and td2 of materials 9 and 10 are equal to each other and smaller than the thickness ts of the material 8. The supporter 4 has no deformation by the temperature change since td1 is equal to td2. The optimum ratio of thickness between material 8 and materials 9 and 10, although varies by the oscillating attenuation capacity and the specific gravity peculiar to the material, is set properly at 8

摘要： PURPOSE:To provide a forming device for thin films which is improved in mass productivity and the distribution of film thickness, by disposing a cylindrical substrate holder so as to intersect with the line connecting the centers between targets at the mid-point thereof and rotating the same around the central axial line. CONSTITUTION:Plural sputtering substrates 8 are mounted to a cylindrical substrate holder 7A and the holder is so disposed as to enclose the centerline connecting the centers of targets 1, 2 in a forming device for thin films by plasma discharge. The holder 7A is disposed with inclination from the vertical line l3 running the mid-point O at the centerline of the targets 1, 2. The substrate 8T located in the upper part of the target 7A and the substrate 8B located in the lower part in this stage assumes a point-symmetrical position relation with the point O. Therefore, if the holder 7A is rotated 180 deg. around the axial line l2 as a rotating axis, the positions of the substrates 8T and 8B are alternated. Sputtering films are stuck uniformly in the sputtering substrates 8 by the above- mentioned device.

摘要： PURPOSE:To hold stably the orientation of magnetization at the initial value, by tilting the magnetization of a magneto-resistance element to the surface of a recording medium and at the same time forming a cut to a part of the magneto- resistance element with the orienting angle of the magnetization of the magneto- resistance element. CONSTITUTION:The magnetizing direction of a magneto-resistance element (MR element) 4 that senses the change of a magnetic field as a change of the resistance value is oriented by angle theta of inclination to the lengthwise direction. At the same time, a cut 5 is given to the back of the element 4 with angle theta. As a result, the counter magnetic field of the element 4 is not in the direction of the height (h) but in the oblique direction (a). Thus the magnetizing direction can be easily held at the initial value theta, and accordingly, a large bias magnetic field is not required for the element 4.

摘要： PURPOSE:To stabilize the rotation, by providing plural small holes for air flow in the side face of outside circumferential parts of spacers of plural built-up flexible discs which are isolated from one another by plural spacers provided with air paths in the direction of the radius. CONSTITUTION:Spacers 2 and discs 1 between side plates, which are not shown in figure, in both sides are constricted by a guide bolt 4 and are made into one body. Air which has the pressure controlled is flowed into a hollow space 8, which is provided in the center of the laminated material, from the external. Several small holes 9 are provided in the side of outside circumferential parts of spacers 2. Controlled compressed air which is flowed into the hollow space 8 passes through air paths of respective spacers 2 as shown by arrows A and is fed to gasp 10 between discs 1. Even if a pressure difference occurs in each gap 10, air is flowed in the axial direction by small holes 9 as shown by an arrow B, and pressures in respective gaps 10 are equal to one another, and the force to deform discs 1 disappears. Thus, gaps 10 of discs 1 are kept constant to stabilize the rotation.
