Abstract

A magnetic disk file having a sealed disk enclosure 10 and an integral drive motor assembly 11 both mounted on a common base casting 12 is slidably located in a subframe 13. The subframe 13 is in the form of a box with guide rails 14 along its lower edge for receiving complementary sliders 15 of the base casting. When fully inserted into the subframe, the casting 12 is supported in three-point fashion by means of the two rear sliders 15 and by a tapered pin (not shown) which locates in an offset hole in the subframe. The entry of the tapered pin into the hole lifts the forward sliders 15 clear of the guide rails 14. Once in place, the casting is secured by means of bolts 16 through the rear sliders. The subframe is divided into upper and lower sections by a shelf structure 17.

Magnetic Disk File Package

A magnetic disk file having a sealed disk enclosure 10 and an integral drive motor assembly 11 both mounted on a common base casting 12 is slidably located in a subframe 13. The subframe 13 is in the form of a box with guide rails 14 along its lower edge for receiving complementary sliders 15 of the base casting. When fully inserted into the subframe, the casting 12 is supported in three-point fashion by means of the two rear sliders 15 and by a tapered pin (not shown) which locates in an offset hole in the subframe. The entry of the tapered pin into the hole lifts the forward sliders 15 clear of the guide rails 14. Once in place, the casting is secured by means of bolts 16 through the rear sliders. The subframe is divided into upper and lower sections by a shelf structure 17. The shelf 17 supports a number of electronic circuit boards 18 for controlling the operation of the file. These are plugged in from both ends of the subframe to an edge-mounted interconnection board 19. The circuit boards are connected by way of edge connectors 20 and cables (omitted for clarity) to the electromechanical portions of the file 10 and 11 mounted on the casting 12.
