ABSTRACT:
A system is disclosed for obtaining read/write head positioning movement and control for a storage disc drive. The rotational energy source for the disc is also utilized for the additional task of indexing the read/write head assembly, thereby eliminating need for a second drive source and associated circuitry. Solenoid actuating means are employed to engage one of two driven rollers with a track position wheel to cause said wheel to rotate in one of two opposite directions. This rotational movement is converted into indexing movement of the read/write head assembly.
