Abstract

This structure provides means for the alignment of a magnetic recording head on a head/carriage assembly. Independent adjustment of the azimuth, radial and tangential position is accommodated. In addition, the head is loosely clamped during the alignment process so that subsequent adjustments do not affect those made previously.

Magnetic Recording Head Alignment Fixture

This structure provides means for the alignment of a magnetic recording head on a head/carriage assembly. Independent adjustment of the azimuth, radial and tangential position is accommodated. In addition, the head is loosely clamped during the alignment process so that subsequent adjustments do not affect those made previously.

Fig. 1 shows the direction of movement for adjustment of azimuth as well as radial and tangential positions.

Fig. 2 is a top view of a head support arm assembly showing the mounting screws 1 which hold the head support arm to the carriage (not shown). The recording head is shown generally at 2. An alignment slot 3 and a hole 4 in the head support arm provide means for accurately positioning the arm on the alignment fixture shown in Fig. 3. The head support arm manipulator 5 includes a spring-loaded alignment wedge 6 which engages slot 3 and a spring-loaded pin 7 which engages hole 4 in the head support arm. These members are spring- loaded so that they will snap into position upon initial engagement with the arm.

The carriage assembly is mounted on the three pins l2, l3 and l4 which form a part of the carriage support bracket l6, and the mounting screws 1 are loosened. The support bracket is moved toward the manipulator until the wedge 6 and pin 7 engage the head support arm. Knob 18 is rotated to correctly position the head support arm in azimuth. Knob 19 is rotated to correctly position the head...
