TWIN TRACK VERTICAL READ-WRITE HEAD STRUCTURE

摘要

TWIN TRACK VERTICAL READ-WRITE HEAD STRUCTURE An improved read-write head for twin track vertical magnetic recording is described. Inductive, solid state, or magneto-resistive sensors may all be employed with the new read-write head structure. A preferred embodiment utilizing a magneto-resistive coupled film sensor for read back which saturates to allow writing is disclosed.
