摘要： A method of data compression for recording data on a recording medium such as a magentic tape, a method of data restoration for data which has been compressed for recording, and an apparatus of data compression and restoration prescribe the data to be compressed based on type or value and encode the compression object data, thereby reducing the number of bits necessary to indicate the compression object data. Compression is implemented only for consecutive data fewer in number of repeating consecutive bytes than a certain number, thereby reducing the number of bits necessary to indicate the number of bytes of the consecutive data. A compression mark indicative of compression is appended to the compressed data, consisting of data made by encoding the compression object consecutive data and data indicating the number of bytes of the data, either at the front or rear of the compressed data, whereby an input data string can be compressed drastically and compressed data, even including errors, can be restored.

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.

摘要： A cleaning apparatus enables a workpiece to be rotated at a high speed over a long period, enables the outer and inner circumferences of the workpiece to be cleaned by a simple structure without provision of a special mechanism, and enables avoidance of formation of scratches in the radial direction of the workpiece. Chuck members 1-1 to 1-3 for chucking the outer periphery of a magnetic disk W are driven to rotate by a brush rotation mechanism 4 and are made to rock back and forth in the radial direction of the magnetic disk W by a rocking portion 6 of the brush rotation mechanism 4. Specifically, the rollers 12 of the chuck members 1-1 to 1-3 are formed by polyurethane foam and a plurality of circumferential grooves 14 are formed in the surface of the rollers 12. The rod-shaped brushes 3-1 and 3-2 are formed by attaching sponges 32 having a large number of bumps 30 to the front ends of shafts 31. The rocking portion 6 makes the sponges 32 rock back and forth so that the bumps 30 at the front end swing out to the inner circumference side of the magnetic disk W and the bumps 30 at the rear end swing out to the outer circumference side of the magnetic disk W.

摘要： A magnetic disk has a magnetic layer and a protective layer disposed on the magnetic layer. A multiplicity of lands having sizes within a predetermined range of sizes and generally equal heights within a predetermined range are formed on the surface of the protective layer at a density within a predetermined range. The lands serve to effectively remove contaminants attached to the floating surface of a magnetic head to ensure a desired sliding reliability and floating stability of the head during a long period of time even in the case of a high-density magnetic disk apparatus in which the extent of floating of the head is small. The reliability with which the magnetic disk apparatus operates is thereby improved. The lands are formed on the surface of the protective layer by a process of forming a mask of fine particles on the protective layer surface and etching the protective layer surface through this mask.
