Abstract: PROBLEM TO BE SOLVED: To reduce a bit error rate.
SOLUTION: An address controller 41 controls read and write addresses for a buffer memory 42 in accordance with a control signal so as to equally include an upper order byte being a code word including only a symbol with a low error rate, and a lower order byte being a code word including only a symbol with a high error rate. Thus, errors occurring during RLL code decoding are equally divided into error correction code words, an error occurrence probability that exceeds an error correction capability in an error correction code word is lowered, and an error rate after error correction can be reduced. The present invention is applicable to a recording and reproducing device for performing encoding that combines two kinds of code words of an RLL code word and an error correction code word with interleave.

Abstract: PURPOSE:To improve a DC magnetization reproduce signal output and to make DC magnetization recording possible at a high speed on the magnetic layer etching type perpendicular magnetic recording disk by removing only the perpendicular magnetic recording layers in the recessed parts of the magnetic recording disk. CONSTITUTION:This magnetic recording disk is formed by laminating the perpendicular magnetic recording layer 3 and a back lining layer 2 having a high magnetic permeability on a nonmagnetic substrate 1. The magnetic layer etching type perpendicular magnetic recording disk with which at least a part of data tracks or servo signal parts are magnetically separated and formed by ruggedness and only the perpendicular magnetic recording parts are removed in the recessed parts is formed. The DC magnetization recording is conducted at a high speed by impressing DC magnetic fields in the perpendicular direction of one or plural sheets of such magnetic recording disks as the magnetic recording method for the magnetic recording disk. As a result, the high DC magnetization reproduced signal output is obtd. In addition, the application to mass production of the magnetic disk device of a high memory capacity is possible.

Abstract: PURPOSE:To suppress the peak shifting rate of a DC magnetization reproducing signal to be small by forming ruggedness magnetic layer patterns on a ruggedness substrate without damaging largely the accuracy of ruggedness patterns formed on the substrate in a substrate ruggedness type magnetic recording disk. CONSTITUTION:In a magnetic recording disk provided with a substrate 1 on which patterns for magnetic recording information are formed with a recessed part 11 and a projecting part 12 which are laid prolongingly while being adjacent each other, a substrate layer 22 formed on the substrate 1 and a magnetic recording layer 23 formed on the substrate layer 22 and comprizing primarily, for example, Co, etc., the ratio d/L of the film thickness (d) of the magnetic recording layer 23 with respect to the minimum width of the recessed part 11 is made to be smaller than 0.15. Thus, since the peak shifting rate of the DC magnetization reproducing signal of a substrate ruggedness type magnetic recording disk 21 is suppressed to be small, this device can be applied to the magnetic disk device of a large storage capacity.

Abstract: PURPOSE:To enable driving of a magnetic recording medium at a high speed without fluttering even if dry wind is blown to the medium while magnetic powder is oriented. CONSTITUTION:The magnetic recording medium 4 constituted by forming a magnetic coating film layer 6 consisting of magnetic particulates on the surface of a nonmagnetic base 5 is supported by plural revolution type guide rolls Da, Db and Dc provided in the orienting magnetic field generated by a pair of orienting magnets 1 and 2 and is driven at a high speed while the medium is exposed to the above-mentioned orienting magnetic field. The dry wind 7 from a dryer 3 for drying is blown to the medium within the orienting magnetic field while said magnetic coating film layer 6 is not dried yet, by which this layer is dried. The fluttering of the magnetic recording medium is prevented by the presence of the revolution type guide rolls even if the drying wind is blown. Since the magnetic recording medium can be taken up stably at a high speed, the productivity is improved.
