THEORY OF OPERATION

is highly unlikely as the system is pre—ten— sioned (reducing angular and linear inertia) to allow greatly improved track to track access times.

Lead Screw Positioning

In some Elite One designs, the stepper motor rotates a lead screw. The four—start lead screw is threaded through a type of "nut" which is part of the read/write head carriage assembly. As the stepper motor rotates, the linearly stationary lead screw forces the “nut” to move, taking the read/write head carriage along with it.

7.1.5. Read/Write Head

The Elite Series read/write heads are single element, glass bonded ferrite/ceramic heads with tunnel erase elements to provide erased areas between data tracks. Thus, normal interchange tolerances between media and drives will not degrade the signal to noise ratio and insures diskette interchangeability.

The read/write head is mounted on a carriage assembly which moves on rails and is positioned by one of the two mechanisms mentioned above. The diskette is held in a plane perpendicular to the read/write head by a platen located on the base casting.
