4. Index Hole (Type 2D Diskette).
5.
The outer circle identifies a hole
in the diskette 2D envelope; the
inner circle shows the index hole
in the diskette. When these two
holes are aligned while the
diskette is turning in the drive,
the D2 Light Emitting Diode (LED)
will transmit light to the D2 Pho-
to Transistor (PTX).
Collet
(Drive Sprindle) Hole.
The
outer
circle identifies the hole
in
the diskette envelope, permit-
ting the
collet
access to
the
diskette. The
inner circle is
where
the
collet
will
come into
contact
with the diskette and
clamp it to the
drive hub.
6. Read/Write Head Opening. The head
opening permits the head access to
the diskette surface. The
read/write head moves along the
length of the opening to a given
position (track) on the diskette.
7. Stress Relief Notches. If the
diskette is accidentally bent, the
stress relief notches will aid in
distributing the stress in the
head opening area.
