STEPPER MOTOR - HEAD CARRIAGE
ASSEMBLY
A stepping operation moves the head
carriage assembly from one track to
another. The head carriage assembly
slides on two guide rods and contains
the read/write head(s). The 24 Volt
DC stepper motor shaft turns 1.8
degrees in either direction under con-
trol of the access signals. This
moves the head carriage one track. A
flexible steel band attached to the·
stepper motor pulley, moves the head
carriage assembly (Figure 7-14).
