NOTICE: This equipment has been designed as a: component to high standards
of design and construction. The product, however, must depend on receiving
adequate power and environment from its host equipment in order to obtain
optimum operation and to comply with applicable industry and governmental
regulations. Special attention must be given by the host manufacturers in the
areas of safety, power distribution, grounding, shielding, audible noise control,
and temperature regulation of the device to insure specified performance and
compliance with all applicable regulations. This equipment is a component sup-
plied without its final enclosure and therefore is not subject to standards imposed
by FCC Rules for Electro-Magnetic Interferance (EMI). Federal Docket 20780/FCC
80-148 Part 15.

mental enclosure (heads, media, actuator, etc.) requires special
facilities. Only the printed-circuit boards, brake and motor
external to the sealed area can be replaced without special
facilities.

1.1
INTRODUCTION
The CDC 9410 FINCHlMDisk Drive is a small, low-cost, medium-performance,
random-access rotating-disk, mass-memory device designed to record and
recover data on up to two rigid eight-inch non-.removeable fixed disk media.
The FINCH uses low-mass flying read/write heads attached to a precisely con-
trolled rotary positioner. It has an unformatted data storage capacity of 8,24 or
32 megabytes, depending upon configuration.

OPERATION

2.1
INTRODUCTION
There is only one mechanical function required of the operator: to ensure that
power is applied. During routine computer operations t the operator should,
of course, note any malfunctions or problems and report them.
2.2 OPERATING AND PRELIMINARY DIAGNOSIS PROCEDURE
Due to the sophisticated design and special equipment required to repair the
FINCH, most repairs may only be effected at a properly equipped and staffed
depot service and repair facility. These repair facilities will be capable of
performing all warranty and routine repair activities.
Because there are no lamps for error or fault indication and no operator / drive
interaction is required, operating systems must contain sufficient error report-
ing information to allow the operator to make preliminary diagnosis of problems.
In other words, software must adequately inform the operator if any technical
difficulties arise. In multi-unit installations, logical and physical identification
are necessary for the oerator to identify a defective unit.
2.2.1
OPERATING INSTRUCTIONS
1.
2.
3.
4.
The following conditions must be met to initiate operation of the disk drive.
a. The DC power cable from the power supply must be connected.
b. Rotary-arm shipping lock must be in operating position.
The operating temperature of the drive is 50
0
to 1040 F (100 to 40
0
C) with
a maximum temperature change of 18
0 F (100
C) per hours.
Additional information on the drive can be found in the Hardware Installation /
Operation Manual 77653532.
In case of a malfunction the unit is to be serviced only by trained personnel.
