A magnetic head/support assembly 10 for assembly into the data access mechanism 70 of a magnetic disk file comprises a magnetic head element 12 and a support structure 11, 20, 21 for the head element. The head/support assembly also comprises a head lead locator 27 including a frame 51 for locating and terminating the leads 15 from the head element 12 remotely from the element. The locator is attached to the support structure and the leads extend across the frame and are retained in fixed spaced apart relationship over a sufficient portion of their lengths to permit direct electrical connection to a correspondingly spaced pattern of conductors on external data channel circuitry carried by the access mechanism.

Magnetic head/support assembly and access mechanism for a disk file

A disk file 10 employs at least two filters 15,16 for removal of airborne particles, one filter 16 having a relatively coarse mesh and a relatively high rate of airflow and the other 15 having a relatively fine mesh and a relatively low rate of airflow. The fine filter 15 may be combined with a third, breather filter 30 which removes particles from air entering the disk enclosure. The main purpose of the coarse filter 16 is to remove the larger, more damaging particles very rapidly, thereby reducing the risk of damage to the surfaces of the disks 12.
