Abstract: A disc-type recording medium arranged to be recorded/reproduced by a recording/reproducing head mounted on a head slider has a predetermined projection and pit pattern on the surface thereof and/or the head slider. In a state where the recording/reproducing head mounted on the head slider and the disc-type recording medium are in contact with each other, recording/reproducing is performed. As a result, abrasion between the recording/reproducing head and the disc-type recording medium can be prevented and an excellent recording/reproducing characteristic can be obtained.

Abstract: A quasi contact head comprises a slider with a flying surface opposed to a magnetic disk. A composite layer is formed on the slider at its trailing end so as to contain a head element such as an MR element. The head element is exposed at an exposure surface formed on the composite layer. A step serves to retract the exposure surface from the flying surface. An edge formed between the step and flying surface is subjected to grinding. The edge wears off during the initial rotation of the magnetic disk, so that the flying height of the slider can be set lower.

Abstract: A glide head using a slider with an outside active rail is described. In one embodiment, the trailing end of the outside rail extends beyond the trailing end of the inside rail. Thus, during use, the trailing end of the outside rail is closer to the surface of the magnetic disk because of the slope of the glide head's flight. Accordingly, the outside rail is the active rail. The inside rail may be wider than the outside rail to compensate for additional lift created by the greater length of the outside rail. In an alternative embodiment, the trailing end of the outside rail extends beyond the trailing end of the inside rail and there are notches located in the side edges of the rails. The notches do not extend to the forward tapered ends of the rails nor to the trailing ends of the rails. The notches provide additional stability during the slider's flight and decrease the air bearing area of the rails as needed for fly height requirements. In addition, the testing time is minimized by the wide trailing ends of the rails.

Abstract translation: 描述了使用具有外部主动轨的滑块的滑行头。 在一个实施例中，外轨的后端延伸超过内轨的后端。 因此，在使用期间，由于滑行头的飞行的斜度，外轨的尾端更靠近磁盘的表面。 因此，外轨是主动轨道。 内侧轨道可以比外侧轨道宽，以补偿由外部轨道的较大长度产生的附加升力。 在替代实施例中，外轨道的后端延伸超过内侧轨道的后端，并且在轨道的侧边缘中存在凹口。 凹槽不延伸到轨道的前锥形端部和轨道的后端。 凹槽在滑块的飞行过程中提供额外的稳定性，并根据飞行高度要求降低导轨的空气轴承面积。 此外，通过轨道的宽尾端最小化测试时间。

Abstract: A method of manufacturing a hybrid type magnetic head slider using a thin film coil in which a number of cores can be manufactured in the sane condition, and improvement and uniformity in yield and performance can be expected. A conductor pattern forming a plurality of thin film coils (2b) and a magnetic material (magnetic cores 2a) passing in the thin film coils are formed on a nonmagnetic base (1) by means of spattering or the like, and grooves (15) for bonding a plurality of ferrite made head cores (13) are formed on a different nonmagnetic base (14). The ferrite made head cores, which are bonded by glass thin films with a fixed gap, are bonded after polished into the outer dimension fitted to the grooves. A thin film coil stick (4) having the thin film coils formed thereon and a head core base (16) having the head cores bonded thereto are combined and bonded together to form a magnetic head slider bond bar (20), which is then cut and subjected to a polishing, whereby a magnetic head slider is completed reducing manual work.

Abstract: In a magnetic head device, I-shaped side and center cores are fitted to a slider, and magnetic gaps are formed by a part of the slider. Therefore, a magnetic path can be shortened, and the magnetic head device is constructed so as not to leave strains on the cores, so that the core loss is low. In addition, a back core (back plate) having a wide area is provided, so that heat-dissipating effect is enhanced. Therefore, magnetic field-generating efficiency can be improved in wide frequency bands. Further, by decreasing the number of turns of a coil, the inductance, the impedance, and the loss factor can be reduced.

Abstract: An apparatus for measuring a maximum static friction force is disclosed, in which the displacement of the relative positions of first and second objects due to the operation of a driving unit is suppressed for measuring an accurate static friction force characteristic. The static friction force measuring apparatus for measuring the static friction characteristic between a first object fixed on a mounting base and a second object in contact with the first object and held in a holder comprises an external force buffer interposed between the mounting base and the mounting base side fixed end of the apparatus, a speed controller arranged in the drive unit for controlling the relative speeds of the holder and the mounting base to a level sufficiently low as compared with the resonance frequency of a frictional force detector, and a device for suppressing the displacement of the relative positions of the first and second objects to such an extent that the external force exerted substantially in parallel with the contact surface between the two objects exceeds the maximum static friction force. The frictional force detector detects the maximum static friction force immediately before the displacement begins between the two objects.

Abstract: The magnetic head disclosed has a slider which comprises a running surface where contact-sliding with respect to a magnetic recording medium occurs, and a polycrystalline silicon film which is provided on at least a portion of said running surface. The polycrystalline silicon film has a thickness of 3 to 10 nm. The running surface is formed of Al.sub.2 O.sub.3.TiC ceramic or silicon. This arrangement is effective in preventing an attraction phenomenon between the head and medium, reducing a frictional coefficient and suppressing damage to the medium.
