    摘要: A magnetic head slider in which a leading pad is projected in a thicknesswise direction of the slider, in comparison with a trailing pad so as to reduce vibration caused by contact between a flat medium surface of a disc and the slider carrying thereon a magnetic head, to reduce variation in flying height caused by wavy unevenness of the medium surface, and to reduce variation in atmospheric pressure around the slider, thereby it is possible to enhance the recording density and the reliability of the magnetic head slider while reducing the costs thereof. Further, a magnetic disc unit using the above-mentioned magnetic head slider.

    摘要: An object of the present invention is to prevent a spacing between a magnetic head and a writing medium at low temperature from increasing to cause a writing/reading error, and to prevent the magnetic head element protruded by a temperature increase from colliding with small protrusions on a magnetic disk surface, and to prevent damage on the element, and to prevent the occurrence of thermal asperity. In order to attain the object, a magnetic head slider is provided, which includes a magnetic head element supported on a rotating magnetic disk via a gap to write or read information on the magnetic disk, and a heat source for heating the magnetic head element. A magnetic disk device is further provided, which includes a magnetic head slider.

    摘要: A head element is made into contact with the surface of a recording medium so as to realize a float-up degree of 5 nm. Accordingly, a slider incorporating the head element for recording and reproducing data to and from the recording medium is provided thereon with a plurality of pads having step parts, and one of the plurality of pads, on which the head element is mounted, has a height which is less than that of the other pads. Thus, the pads other than the pad on which the head element is mounted are floated up while the pad on which the head element is mounted is stably made into contact with the surface of the recoding medium by means of a meniscus suction force and a damping action of lubricant applied on the surface of the recording medium.

    摘要: In a magnetic disk apparatus, mounting of plural heating elements to a magnetic head slider is permitted. Thermally assisted magnetic recording from inner to outer surface is permitted at a small amount of power consumption. In one embodiment, the magnetic disk apparatus has a magnetic disk on which magnetic information is recorded, a magnetic head slider having an air bearing surface for floating from the magnetic disk in proximity thereto, and a rotary actuator moving over the disk arcuately while supporting the magnetic head slider by a suspension. A recording element acting to record magnetic information on the magnetic disk, a playback element acting to play back the magnetic information recorded on the magnetic disk, and plural heating elements acting to locally heat the magnetic disk are carried on the magnetic head slider. A circuit for switching energization to the plural heating elements and according to information about the direction of a DC power supply VH, frequency contained in an AC power supply, or the like is formed.

    摘要: Embodiments of the invention achieve a decrease in electric power consumption while ensuring high recording density and high reliability in a magnetic disk apparatus. In one embodiment, a magnetic disk apparatus comprises a rotatable magnetic disk and a magnetic head slider to be able to fly above a surface of the magnetic disk. The magnetic head slider comprises an air bearing surface, by which the magnetic head slider is caused to fly and come near to the rotating surface of the magnetic disk with a predetermined spacing therebetween, recording and reproducing elements to perform at least one of recording on and reproduction from the magnetic disk, and a heating device to adjust a distance between the recording and reproducing elements and the surface of the magnetic disk. The heating device is mounted such that heating thereof causes a part of the air bearing surface to expand and project to increase a distance between the recording and reproducing elements and the surface of the magnetic disk.
