Abstract
Tape guides for a magnetic tape cassette comprise a half of cylindrical tube each adapted to fit securely over a support post within the housing of the cassette. The method of manufacturing the guides consists of forming thin-walled portions as grooves on at least the inner or outer side of a tube, with or without inwardly protruding ribs, which facilitate the division and provide a tight fit of the half piece to the post, and then dividing the tube along the plane into two halves. The tube is made of a metal, particularly brass or stainless steel, or plastics and formed by drawing or other irregular-shape forming technique, with polishing, plating, and/or precision polishing before division.
