Before Recording or Playing Back a Cassette
Tape
A tape that is loose or slack inside the
cassette case may become wound around
the capstan or pinch roller. To avoid this
problem, check and tighten (if necessary)

Protection of Recorded Tapes
Pre-recorded cassettes can be protected
against accidental erasure or re-recording by
removing the "punch out" record tab as
shown in figure F. Each cassette contains
two record tabs, one for each side of the
tape. With Side A (or 1) of the cassette
facing up as shown, the record tab for Side
A is on the right end of the cassette case and
the record tab for Side B is on the left end.
When this tab is removed and the cassette
inserted into a tape deck the deck cannot go
into a record mode because the deck has a
special sensing arm which checks for the
presence of this tab. If the tab is removed,
the record and erase functions are inhibited
and the tape cannot be re-recorded. If the
tab is removed, (using a screwdriver as
shown) and later the recordist decides to
re-record the cassette, a piece of tape can be
placed over the tab hole to allow recording
(Fig. F, G).
Use Both sides of the Cassette
Both sides of the cassette tape can be
recorded (or played). See fig. A. The cas 
settes are usually marked Side A (or 1) and
Side B (or 2) for reference. To change sides
of the cassette to be recorded or played,
simply remove the cassette from the deck
(using the EJECT Key) and turn it over.
The cassette tape can be recorded in either a
monophonic or stereo format. The various
record and playback procedures as well as
the head configurations have been stan 
dardized for compatibility. See the Stereo/
monophonic head fig. B.
Recording Time
Cassette recording tapes are wound on reels
in a special convenient case that is easily
inserted into the cassette deck. The tape
width, cassette container shape and size and
the tape speed are standardized for com 
patibility. The standard C-60 cassette tape
contains enough tape for 60 minutes of
recording. The C-30, C-90 and C-120 cas 
settes contain enough tape for 30, 90 and
120 minutes respectively. (All times are
total times when using both sides of the
tape.)
Choice of Tapes
TEAC tape decks are designed to work well
with a wide variety of cassette tapes.
Chromium dioxide (CrO 2 ), Ferri chrome
(FeCr) and HiFi tapes can be used with
excellent results. Cr0 2 and FeCr tapes
generally require higher bias and give im 
proved high frequency response. The longer
tape lengths such as C-120 and C-180 are
very thin and are easily damaged. We do not
recommend them for high fidelity
recording.
For good stereo recording we recommend
that you use only good quality, name brand
tapes. Also the pinch roller and capstan
must be kept very clean to insure proper
operation.
