Abstract

1276004 Magnetic head supports INTERNATIONAL COMPUTERS Ltd 23 Feb 1970 [12 March 1969] 12928/70 Heading G5R A magnetic head 1 is resiliently supported 18 from a pad 12 having apertures 5, 7 connected 11 to a source of fluid above ambient pressure to space the pad from a record 14 while allowing the head 1 to make light contact. The resilient support 18 may be a slotted diaphragm allowing limited axial and pivotal movement, and the space above maintained below ambient pressure via line 21 to determine the record/pad spacing. Alternatively, the pad may be subject to spring and/or gravity forces to balance the fluid pressure. The pad is supported in a gimbal arm 12 movable to change tracks and the fluid may be air containing iso-propyl alcohol as a lubricant.
