摘要： PURPOSE:To improve the flying characteristic of a slider and, at the same time, to prevent the deterioration of the magnetic characteristic of the slider during its manufacturing process by constituting the slider of a specific amorphous carbon material and specifying the surface roughness of the surface of the slider facing a recording medium to a prescribed value. CONSTITUTION:The slider 2 of this magnetic head 1 is constituted of an amorphous carbon material having an apparent density of >=1.70g/cm and the surface roughness of the surface of the slider 2 facing a recording medium is set to 30-500Angstrom . As a result, the wear of the surface can be reduced when the slider slides on the recording medium and the flying characteristic of the slider 2 can be stabilized. In addition, since the surface can be easily roughened when the slider is heat-treated in an atmosphere containing oxygen or hydrogen, the deterioration of magnetic characteristic of a core caused by the formation of unevenness can be prevented. Moreover, it is preferable to subject the surface of the slider 2 facing the recording medium to hydrophilic or hydrophobic treatment.

摘要： PURPOSE:To obtain the process for producing the magnetic recording medium which can improve coercive force without decreasing or losing the thickness of a protective lubricating layer by forming a magnetic material layer of a Co-based alloy on a titanium substrate, then subjecting the layer to a heat treatment at a prescribed temp., then forming the protective lubricating layer. CONSTITUTION:The titanium material is first formed to a substrate shape for a magnetic disk and is subjected to prescribed end face finishing and surface polishing to form the substrate for the magnetic disk. A Cr layer 2 and the CoNiCr magnetic material layer 3 are successively formed on this titanium substrate 1 under the condition of 250 deg.C substrate temp. by a D.C. magnetron sputtering device. The resulted substrate is subjected to the heat treatment under the condition of 500 deg.C X 10 minutes in an atm. atmosphere. The C protective lubricating layer 4 is thereafter formed on the CoNiCr magnetic material layer 3 under the condition of 250 deg.C substrate temp. by the D.C. magnetron sputtering device.

摘要： PURPOSE:To obtain a thermal head which has excellent wear resistance and thermal shock resistance by a method wherein for a wear resistant layer, silicon carbide is used, and the component ratio between C and Si for the silicon carbide is continuously or discontinuously changed in the thickness direction of the wear resistant layer so that the component ratio at a heating resisting body side becomes minimum. CONSTITUTION:On an earthing electrode 12, a substrate 1 is placed, and from a gas inducing port 10a, a mixed gas which is composed of C2H4 as a hydrocarbon gas and SiH4 as a hydrogen silicide gas is induced in a decompression chamber 10 while the mixing ratio of the mixed gas is being changed. When a prescribed voltage is applied to an electrode 11, carbon C and silicon Si in the hydrocarbon gas and hydrogen silicide gas which have been excited by the applied voltage adhere to the substrate 1 in accordance with a mixed component ratio y/x, and on the surface of this substrate 1, a wear resistant layer 6, which is composed of SixCy, is formed. For example, the component ratio at a heating resisting body 3 side is taken as y/x=0.6, and the y/x value is gradually made larger in the thickness direction of the wear resistant layer 6, and at the surface, it is made to be y/x=2.8.

摘要： PURPOSE:To equip an excellent durability against thermal shock by a method wherein between a heating resisting body layer, and a wear resistant layer, a thermal relaxation layer which has a hardness lower than the wear resistant layer and also has electric insulating property is provided. CONSTITUTION:On the upper surface of a substrate 1, a glazed glass layer 2, a heating resisting body layer 3 and electrode 4 are laminated in order, and at the same time, on the electrode 4, a thermal relaxation layer 6 is laminated. This thermal relaxation layer 6 is coated with a wear resistant layer 5 which makes contact with heat-sensitive paper. For example, the thermal relaxation layer 6 with a film thickness of 2mum is formed on the electrode 4 with silicon oxide with Knoop hardness 800, on this thermal relaxation layer 6, the wear resistant layer 5 which becomes AC with a film thickness of 2mum can be formed without trouble. Therefore, heat generated by the heating resisting body is transmitted to the wear resistant layer through this thermal relaxation layer 6. In the meantime, since this thermal relaxation layer 6 has an electric insulating property, the electrode does not short circuit, etc.

摘要： PURPOSE:To easily detect the optical axis position of a light beam with high accuracy without executing intricate signal processing by using a photoelectric converter with which the output current value corresponding to the incident position of the light beam from an end part is obtd. CONSTITUTION:The device is so constituted that the light beam L emitted from a laser light source 1 passes the optical system 2 and that the prescribed position of a prescribed object is irradiated with this light beam by driving and adjusting the optical system 2 by a driving part 3. A beam splitter 4 is disposed on the optical axis of the light beam L for adjusting the position of the optical axis of such light beam L in the direction (x) orthogonal with the optical axis and a part of the light beam L is reflected 90 deg. and is introduced to a DIP sensor 5 as the photoelectric converter. A control command is then transmitted to the driving part 3 in order to adjust the optical axis of the light beam L with respect to the position in the direction orthogonal with the optical axis in accordance with the incident position (x) of the light beam L and to adjust the optical axis of the light beam L with respect to the position (z) in the optical axis direction in accordance with the dispersion of the light beam La computed by an arithmetic part 5. The optical axis of the light beam is automatically adjusted to an arbitrary position in this way.

The primary and secondary outputs of the scatter ing beam S are obtained by the sensor 5 and an operation part 6 and dispersion is calculated from said outputs. The particle size and density of the particles 3 are measured on the basis of the dispersion and luminous intensity at a quick response speed with good accuracy.

摘要： PURPOSE:To obtain a magnetic disk whose coercive force is high. CONSTITUTION:A Cr substratum layer, a Co-based allay magnetic-substance layer and, e.g. a Zr layer as a layer for protective use are formed sequentially on a substrate; after that, this assembly is heat-treated at a temperature of 250 deg.C or higher. By this heat treatment, the Zr layer is changed to an oxide and functions as a protective layer. The compound of Zr with, e.g. Cr as a nonmagnetic element in the Co-based alloy magnetic-substance layer is not produced. As a result, the segregation of Cr to the grain boundary of the Co- based alloy magnetic-substance layer is promoted further. Thereby, magnetic interaction between individual crystal particles in the Co-based alloy magnetic- substance layer is weakened, and a magnetic disk whose coercive force is high can be obtained.
