  • Electrically isolated tape guide
    Patent number: 8982509
    Abstract: An electrically isolated tape guide that includes a tape roller having spaced apart flanges extending out from the tape roller for passing magnetic tape between the flanges, and an electrically non-conductive pin having a first end coupled to a center opening of the tape roller to allow the tape roller to rotate about the pin and a second end for coupling to a chassis of a tape drive.

  • Coatings for tape guides
    Patent number: 8210463
    Abstract: A guide for guiding a magnetic data storage tape has a curved support portion for supporting a major tape surface and at least one flange adjoining the support portion. At least in a region of transition between the support portion and the at least one flange, the guide has an under coating of a diamond like carbon material, tungsten carbide, or similarly wear resistant material, and a surface coating having lower surface tension than the under coating. A tape guide apparatus and a method of making a tape guide are also disclosed.

  • Recording and/or reproducing device comprising a coated tape guide
    Patent number: 6873495
    Abstract: A recording and/or reproducing device (1) includes at least one tape guide (10) having a guide wall (13) and guide flanges (14, 15) projecting beyond the guide wall (13). The guide wall and guide flanges are coated with a coating (21) of zirconium nitride or titanium nitride. This results in the tape guide having a high wear resistance and a high resistance to the deposition of material abraded from the tape.

  • Tape guide with wear resistant coating
    Publication number: 20030218092
    Abstract: A tape guide in which the corner geometry between the flanges and the hub prevents the tape from abruptly bumping the flange and in which the corner is coated with a very hard wear resistant material such as zirconium nitride, tungsten carbide, silicon nitride, chromium nitride or diamond like carbon.
