Abstract: PURPOSE:To easily provide a recording medium substrate having a desirable surface profile by supplying water at the time of polishing in the case where a carbon substrate is subjected to texturing by polishing with a tape. CONSTITUTION:The glassy carbon to be used as the recording medium substrate is formed by curing a thermosetting resin and baking this resin to carbonize and is then subjected to finish polishing and the texturing treatment. The texturing treatment is executed by the polishing tape 3 which is pressed by a contact roller 2 under a prescribed working pressure to the glassy carbon substrate 1 rotating at a constant speed. The roller 2 is oscillated at need and the tape 3 is fed at a specified speed during the working. Water is dropped by gravity between the tape 3 and the substrate 1 toward A. As a result, the substrate having the desirable surface profile which is the cause of a difference in recording and reproducing characteristics is obtd. Since cutting oil is not required, the need for excess operations is eliminated.

Abstract: PURPOSE: To obtain a magnetic recording medium having excellent durability and environment stability by specifying the skewness on the front surface of a carbon substrate as a base and forming a lubricant layer by gaseous phase reaction atop this substrate. CONSTITUTION: A magnetic layer 3 is arranged via a ground surface layer 2 atop the carbon substrate 1 as the base and the hybrid lubricant layer 5 is disposed atop the magnetic layer 3. The surface of the substrate 1 is so formed that the max. value and min. value of the skewnesses expressed by equation exist in a range of -1 to 4 and the average value thereof is within a range of 0 to 3. The lubricant layer 5 is formed by the gaseous phase reaction. In the equation described above, Yi denotes the distance from a center line to the peak top or valley bottom; Rq denotes the root mean square roughness and (n) denotes the number of data of Yi. As a result, the errors occurred at the time of reproducing and erasing of recording are decreased and the durability and environmental stability of the recording medium are improved.

Abstract: PURPOSE:To provide the recording medium having the low flying height of a head and excellent CSS durability by providing the surface of a carbon substrate having surface roughness of a prescribed value with a recording film. CONSTITUTION:Glassy carbon is produced by executing a first treatment at about 1000 to 1400 deg.C in an inert atmosphere, then executing a second treatment to make heat treatment at about 1500 to 2000 deg.C under about >=1000atm. The magnetic recording medium is produced by using such carbon. The magnetic recording medium which has high bending strength, is substantially free from cracking and chipping in the production stage for magnetic disks, is as light as 1.6 to 1.8 density, has small intrinsic resistivity, high corrosion resistance and weatherability and high hardness and is nonmagnetic is thereby obtd. The carbon substrate having a trough-shaped surface is formed and the surface roughness of about 40 to 100Angstrom center line average height and about 1 to 6 Rp/Ra with the center line height as Rp is obtd. by a texturing technique using a polishing tape and free abrasive grains. The recording medium having the low flying height of the head and the excellent CSS durability is obtd.

Abstract: PROBLEM TO BE SOLVED: To inspect irregularity defect on the surface of a board to be inspected, such as a carbon board for hard disc automatically with high accuracy and a high efficiency. SOLUTION: A board to be inspected, which is stored in a cassette 51 for supply, is supplied to a turning table 56, which carries the board at a board supplying and carrying-out station A, and defect in its surface is inspected at a surface inspection station B. The front and back of the board are reversed at a reversing station, and it is sent to a back surface inspection station D to conduct defect inspection of the back surface. In the defect inspection, parallel light is radiated in the perpendicular direction to the surface to be inspected of the board to shoot the reflection of the parallel light for the detection of irregularity defect of the board surface as a contrast abnormal part. The number of the detected picture elements of detected defect is converted to a value equivalent to the number of missing errors at the time of using the board in media, a rank is determined based on the converted value, the inspected board is stored in the cassette 51 corresponding to the rank.
