    摘要: There is provided a magnetic disk apparatus comprising: at least one magnetic disk having a magnetic layer and a surface protective layer on a substrate; a magnetic head which faces the magnetic disk in a rotating state with a micro gap and is supported by a slider; rotating means for rotating the magnetic disk; and a actuator for moving and positioning the magnetic head to a predetermined position on the magnetic disk, wherein a plurality of protrusions each having a flat surface are formed in at least a region on the surface of the magnetic disk where a contact start/stop operation can be executed. According to the above magnetic disk apparatus, since the frictional force between the disk and the head is small and the flying height of the head can be reduced and the good floating stability is obtained, so that the excellent recording and reproducing characteristics are derived. Further, protrusions are formed on the protective layer of the magnetic disk and the protrusion shapes are changed in a accordance with a radial position of the magnetic disk depending on the flying height of the magnetic head. According to the above magnetic disk apparatus, since the change of spacing can be set smaller than the change of the flying height, high recording density can be achieved.

A height of each of the protrusions is not less than 5 nm and not greater than 40 nm, and is within ±30% of an average height of the protrusions. A density of the protrusions is not less than 200/mm2 and is not greater than 250,000/mm2. A width of a surface of each of the protrusions in a radial direction of the magnetic disk is not less than 0.1 &mgr;m and is not greater than 10 &mgr;m. The protrusions are discrete protrusions aligned in a spiral direction of the magnetic disk at a predetermined spacing in the radial direction of the magnetic disk. The at least one region of the surface of the magnetic disk includes flat areas between the protrusions. At least some of the flat areas extend continuously from an inner redius of the at least one region of the surface of the magnetic disk to an outer radius of t he at least one region of the surface of the magnetic disk.

    摘要: This invention relates to the magnetic recording medium, its manufacturing method and the magnetic disk apparatus, in which the ferromagnetic thin film is formed on the substrate board, and the protective layer is provided on that. A Magnetic recording medium of the has at least one layer of the protective layer on the magnetic surface, which is characterized in that the surface of the protective layer is provided with the high noncontinuous large resistance layer, and the density of the surface of the protective layer is higher than other regions other than the said surface. The magnetic recording medium has the surface of the protective layer which contains at least one kind or more of the element of the inert gas element, the halogen element and hydrogen. Therefore, when making a lower flying height of the magnetic head is achieved, the slide durability over the long term is improved, particularly, the slide durability of the magnetic disk apparatus using the MR head can be improved.

    摘要: In a magnetic disk unit, in the control of a load/unload function of a magnetic head relative to a magnetic disk, the magnetic disk and the magnetic head are prevented from contacting each other and damage thereto is avoided by utilizing a shallow dual-step subambient pressure slider and carrying out loading/unloading at a rotational speed lower than a rated rotational speed of the normally operated magnetic disk at which writing and reading (R/W) of data to and from the magnetic disk by the magnetic head is normally carried out.
