Claim 1

A device for smoothening (burnishing) operative surfaces of disks for disk memories such as magnetic disks for magnetic disk memories, comprising: a circular-cylindrical-shaped body having opposed planar base surfaces; and at least one sharp-edged groove positioned on at least one of said planar base surfaces.

Claim 2

A device for smoothening (burnishing) operative surfaces of disks for disk memories such as magnetic disks for magnetic disk memories, comprising: a circular-cylindrical-shaped body having opposed planar base surfaces; and at least one sharp-edged groove positioned on at least one of said planar base surfaces.

Claim 7

A method of smoothening (burnishing) operative surfaces of magnetic disks for magnetic disk memories, comprising: mounting a circular-cylindrical-shaped body having opposing planar base surfaces with at least one sharp-edged groove positioned on at least one of such planar surfaces in a support mount similar to a magnetic data-head support mount of a magnetic disk memory so that a planar base surface of said body having said groove therein is uncovered; contacting said uncovered planar surface having said groove therein with an operative surface of a magnetic disk requiring smoothening; and pressing said circular-cylindrical-shaped body via said support means against said operative surface of the magnetic disk while substantially simultaneously providing relative motion between said body and said disk.

Claim 8

A method of smoothening (burnishing) operative surfaces of magnetic disks for magnetic disk memories, comprising: mounting a circular-cylindrical-shaped body having opposing planar base surfaces with at least one sharp-edged groove positioned on at least one of such planar surfaces in a support mount similar to a magnetic data-head support mount of a magnetic disk memory so that a planar base surface of said body having said groove therein is uncovered; contacting said uncovered planar surface having said groove therein with an operative surface of a magnetic disk requiring smoothening; and pressing said circular-cylindrical-shaped body via said support means against said operative surface of the magnetic disk while substantially simultaneously providing relative motion between said body and said disk.

Claim 9

A method of smoothening (burnishing) operative surfaces of magnetic disks for magnetic disk memories, comprising: manually pressing a circular-cylindrical-shaped body having opposing planar base surfaces with at least one sharp-edged groove positioned on at least one such planar surface against an operative surface of a magnetic disk requiring smoothening so that a planar surface of said body having said groove therein is in contact with said disk surface, and providing relative motion between said body and said disk.

Claim 10

A method of smoothening (burnishing) operative surfaces of magnetic disks for magnetic disk memories, comprising: manually pressing a circular-cylindrical-shaped body having opposing planar base surfaces with at least one sharp-edged groove positioned on at least one such planar surface against an operative surface of a magnetic disk requiring smoothening so that a planar surface of said body having said groove therein is in contact with said disk surface, and providing relative motion between said body and said disk.

Claim 11

A method of smoothening (burnishing) operative surfaces of magnetic disks for magnetic disk memories, comprising: pressing a circular-cylindrical-shaped body having opposing planar surfaces with at least one sharp-edged groove positioned on at least one of such planar surfaces against an operative surface of a magnetic disk to be smoothened so that a planar surface of such body having said groove therein is in contact with said operative surface of the magnetic disk while providing relative motion between said body and said disk; scanning the surface of the disk being smoothened with a magnetic data-head equipped with a piezo-electric element at the radius of such disk surface at which said body just happens to be located at, said data-head being equipped with a piezo-electric element being matched in its flight properties to the flight properties of a standard data-head which is later to scan the disk surface in normal operation; and monitoring electrical signals generated by said piezoelectric element during contact between said data-head equipped with said piezo-electric element and said disk being scanned until a desired number of signals are attained.

Claim 12

A method of smoothening (burnishing) operative surfaces of magnetic disks for magnetic disk memories, comprising: pressing a circular-cylindrical-shaped body having opposing planar surfaces with at least one sharp-edged groove positioned on at least one of such planar surfaces against an operative surface of a magnetic disk to be smoothened so that a planar surface of such body having said groove therein is in contact with said operative surface of the magnetic disk while providing relative motion between said body and said disk; scanning the surface of the disk being smoothened with a magnetic data-head equipped with a piezo-electric element at the radius of such disk surface at which said body just happens to be located at, said data-head being equipped with a piezo-electric element being matched in its flight properties to the flight properties of a standard data-head which is later to scan the disk surface in normal operation; and monitoring electrical signals generated by said piezoelectric element during contact between said data-head equipped with said piezo-electric element and said disk being scanned until a desired number of signals are attained.
