Abstract

Fig. 1a shows a detail of a head assembly in which two record/playback heads 1 and 2 are supported from an arm 3 by two spring supports 4 and 5. In use, the head assembly is located between adjacent disks of a disk pack with the spring supports providing the loading force for the heads against the surfaces of the disks.

Recording Head Retraction Tool

Fig. 1a shows a detail of a head assembly in which two record/playback heads 1 and 2 are supported from an arm 3 by two spring supports 4 and 5. In use, the head assembly is located between adjacent disks of a disk pack with the spring supports providing the loading force for the heads against the surfaces of the disks.

The tool shown in Fig. 1b is used to hold the heads in an unloaded condition, while the heads are inserted between the disks during assembly and whenever the heads are needed to be withdrawn from between the disks. The tool consists of two inwardly sprung leaves 6 and 7 supported spaced apart and generally parallel to each other by a spacer block 8. The free ends of the leaves 6 and 7 however are inclined towards each other.

A spreader bar 9 is supported between the leaves 6 and 7 on the end of a rod 10 which passes through a hole in the spacer block 8.

The size of the spacer bar 9 is such that it just fits between the parallel portions of the two leaves 6 and 7 and when in the position shown in Fig. 1b holds the open ends of the leaves 6 and 7 sufficiently wide apart so that they can be fitted over the fixed ends of the head spring supports 4 and 5 shown in Fig. 1a.

In use, the open ends of the leaves 6 and 7 of the tool are placed over the head spring supports 4 and 5 as shown in Fig. 2a with the spacer bar 9 abutting the arm 3. The spacer block 8 is then moved towards the arm 3 sliding the leaves 6 and 7 over the...
