Abstract
A tape guide that has textured surface over which the tape passes. The textured surface has a surface roughness exceeding the flying height of the tape above the surface. This new irregular surface topography reduces the air bearing and allows limited contact between the tape guide and the tape while minimizing tape distortion that can occur with other surface topographies.
Claims8
A tape guide, comprising:
- a hub having a surface over which a tape passes and spaced apart parallel flanges extending out from the hub, the surface comprising a laser texture that includes an array of surface irregularities produced by melting and recrystallizing tiny areas on the surface of the hub.
A roller guide, comprising:
- a hub having a surface over which a tape passes and spaced apart parallel flanges extending out from the hub, the surface comprising a laser texture that includes an array of surface irregularities produced by melting and recrystallizing tiny areas on the surface of the hub.
