Abstract

Fig. 1 shows an actuator mechanism for supporting and moving a plurality of recording heads from one transducing position to another over the surfaces of disks in a multiple disk file. The actuator is constructed so that each head support may be individually removed at will, and when reassembled is accurately located with respect to the disks by a simple clamp.

Disk File Actuator

Fig. 1 shows an actuator mechanism for supporting and moving a plurality of recording heads from one transducing position to another over the surfaces of disks in a multiple disk file. The actuator is constructed so that each head support may be individually removed at will, and when reassembled is accurately located with respect to the disks by a simple clamp.

The actuator consists of a hub 1 mounted for rotation about a shaft 2. Each support arm 4 (only one shown for clarity) is located in two grooves 5 and 6 machined in the hub 1 and also in a slot 7 provided at right angles along the edge of a support frame 8 attached to the hub 1. Each arm 4 is clamped in place by a draw clamp 9 which passes through a hole 10 in the hub 1 and is located in a clamping slot 11 in the arm 4.

An arm 4 is shown separately in Fig. 2 from which it is seen that the act of tightening the draw clamp exerts a force in the direction of arrow 12, locating the indicated surfaces 13 and 14 of the arm against the back machined surfaces of the grooves 5 and 6, respectively, and the indicated surface 15 against a machined edge 16 of the support frame 8.

A cross section of the hub 1, a draw clamp 9, and an arm is shown in Fig. 3 from which it is seen that a chamfered edge 17 of the draw clamp cooperating with a corresponding edge 18 in the slot 11 has the effect of biasing the arm 4 in the direction of arrow 19, so that indicated surfaces 20 and 21 of the arm abut the upper...
