  • Method for preparing a glass spacer ring for a magnetic disk and spacer ring
    Publication number: 20060039080
    Abstract: A glass spacer ring is prepared into a round slice from a glass tube having an outer diameter and a wall thickness corresponding to an outer diameter and a width of the spacer ring, respectively, by engraving a cutting line 7 on an inner side of a glass tube with a cutter in a direction perpendicular to a tubular axis thereof at a cutting interval corresponding to the thickness of a space ring, and heating the cutting line 7 with a burner from an outer side of the glass tube to cut the glass tube by heat shock.

  • Mounting member made of glass for a magnetic disk and method for fabricating the same
    Patent number: 6992858
    Abstract: A glass ring 2, which includes an inner peripheral surface 4, an outer peripheral surface 3 and annular contacting surfaces 5 for contact with magnetic disks and is formed in a ring shape having a rectangular vertical cross-section, is fabricated. The glass ring has at least the contacting surfaces 5 lapped and then etched to have a desired surface roughness so as to improve a surface property. Additionally, the roughened surfaces of the etched contacting surface have an electrically conductive film 6 formed thereon, providing a spacer ring.
