In a tape path where a threading path other than circular is required, a radial threading arm cannot be used. Radial threading is desirable because it is simple to implement, but it restricts what can be done with the tape path. For example, the path shown in Fig. 1 permits the front coat of the media to contact only the head. The back side goes over the other guiding components where damage is more likely to occur. The non- circular dashed path shows how the threader arm in Fig. 2 could accomplish the threading. The arm shown in Fig. 2 works as follows: The solenoid pulls the retractable part of the arm in against the spring. The retraction and extension can be made as slow and smooth as desired by merely ramping the voltage to the solenoid.
