Abstract:
A magnetic data recording and retrieval system, comprising:a housing; at least one magnetic disk having an upper surface and a lower surface and rotationally mounted within said housing; a plurality of heads, each including at least one read element and at least one write element and each having a plurality of head electrical contacts, said head electrical contacts all being of a single configuration common to all of said plurality of heads; a plurality of long tail trace suspension assemblies for connection with said plurality of heads, at least one of which is an upward facing head and at least one of which is a downward facing head, each of said plurality of long tail trace suspension assemblies having a distal end and a proximal end, said distal end having distal long tail trace suspension contacts which connect to said head electrical contacts of one of said plurality of heads, and said proximal end having proximal long tail trace suspension contacts, and electrical trace circuitry connecting said distal long tail trace suspension contacts and said proximal long tail trace suspension contacts; and said long tail trace suspension assemblies including circuitry which is configured to compensate for the orientation of said electrical contacts in said upward facing head as compared with the orientation of electrical contacts of said downward facing head, where said upward facing head and said downward facing head both have a single configuration of contacts.
