ELITE SERIES USER MANUAL 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 sta-
tionary 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.
