Disc Pack Cleaning Table Saves Computer Time 
The disc pack holding table, shown in the figure, 
is a support frame upon which a computer disc pack 
may be loaded and the protective cover released. The 
joining of a disc pack support frame and cover release 
mechanism into a single off-line maintenance support 
unit is both time-saving and useful, permitting manual 
off-line cleaning of the disc pack storage units. This 
combination will eliminate the current practice of 
employing an on-line disc drive unit to hold the disc
pack during cleaning, and should interest designers 
and manufacturers of computer accessories. 
The disc pack cleaner has a portable base with a 
rotating cone to hold the disc pack for cleaning. A 
spring loaded pin is activated by a thumb lever which 
releases the plastic dust cover. The cover is held in 
place by spring loaded balls, permitting removal for 
cleaning the disc pack. The advantage of this arrange-
ment is that disc packs can be cleaned at any time

without shutting down the computer. Prior methods 
required the customer engineer to power-off the disc 
drive in order to clean the pack; scheduling of the 
computer for cleaning was nearly impossible to main-
tain. With this new device, disc packs can be cleaned 
on a definite schedule, and no extra equipment is re-
quired.
