Claims

[Scope of utility model registration request]

In a tape drive body made of an alloy of a soft metal material and a hard metal material, a rough surface portion free from minute latches and distortion is formed on the peripheral surface of the body other than the vicinity of the sliding surface with the bearing. A tape drive body characterized in that the above-mentioned soft metal material is exposed in the concave portion of the rough surface portion, and the above-mentioned hard metal material is exposed in the protrusion portion.
