Abstract
An edge guide is provided for use in a narrow-track linear transport recorder. The guide forms a straight edge near a magnetic head for referencing the location of a magnetic tape with respect to the head. when a coaxial-reel tape cassette is inserted into the recorder, a pair of conical rollers provided in the cassette for use with the guide cooperatively urge an edge of the tape against the guide. The edge guide extends substantially the full distance between the rollers to minimize any tendency of the tape to buckle as it is urged against the guide. A tape drive engages the tape at a position outside of the span between the rollers to move the tape past the head without interfering with the cooperative action of the rollers and the edge guide. Thus, the critical edge guide requirements for narrow-track recording are met entirely outside of the mass-produced cassette.
