m a t i o n . The Computer Memories
                                                                     Performance Specifications:
CM-7000 series of Winchester disk drives
offers exceptionally high storage capacities                                                                CM-7660       CM-7880
in a minifloppy size package. The CM-7000
series is offered in 60 and 80 Mbyte ver-
sions, with an average access time of only
40 msec. The intelligent integration of
Winchester technology with solid and
proven design techniques assures the OEM
the ultimate in quality and reliability, thus
profitability.

     System integration is simplified
because the CM-7000 series have the
identical physical dimensions and mount-
ing hole locations as a standard 5 lA inch
floppy disk drive. DC voltage requirements
are also the same as a mini-floppy drive,
thus permitting the use of the same power
supplies for both types of drives.
                                                                     Functional Specifications:
      The exceptionally high capacities,
performance and features of the CM-7000
series are achieved through the use of a
closed loop servo positioning system, on-
board microprocessor, step-pulse buffering,
head velocity profile control, narrower
track width and gap length manganese zinc
heads, parking zone, head locking mecha-
nism and associated electronics as well as
innovative mechanical design. Utilization                            Physical Specifications:
of a swing-arm actuator used in concert
with the appropriate electronics and head
configuration achieves a track density of
1173 tpi and a bit density of 9275 BPI.
