•• 1-1/2 mil base (50/it hick) tape is suggested exclusively for use with 2-track decks,
and is not recommended for 4-track decks.
The Tape
The length of tape (and subsequently its recording time) is
based upon the size of the tape reel, its hub size, and the
thickness of the tape’s base material. The use of 1 mil base
tape is recommended for 4 track stereo high-fidelity record¬
ing. Polyester base tape is preferred for use in humid or
extremely dry areas.
Two recording speeds are provided on your deck, 3-3/4 and
7-1/2 inches per second. Generally, the 7-1/2 ips recording
speed offers slightly better performance. TEAC decks, how¬
ever, record with excellent quality at the slower 3-3/4 ips
speed giving you maximum tape economy.

Selecting the tape and reel
For recording, new tape is not necessarily needed. If the
tape is of good quality the erase head will erase the previous
recording as the new recording is made. However, avoid
using tapes whose coating is worn, peeled off or stretched.
Good quality tape properly wound
Tape condition can be judged by appearance when
wound on the reel and viewed from the side.
1) Is it neatly wound? 2) Are there steps or irregularities
in the winding? 3) Is the color of the base uniform as seen
from the side. 4) Is the tape edge smooth?
Fungus Indicates old tape stored for a length of time under
high humidity. Sections where the splicing tape has been
applied are especially prone to support fungus growth.
Creases extending from the center positively indicate
uneven stretching. This is caused by differences in tem¬
perature and humidity as well as “stop and start” winding
with some layers wound at the Fast Speed and others at the
play speed.
If the color of the winding is different throughout the reel
it is an indication that two different types of tape have
been spliced in. In some cases, the color may differ
according to production lot even for the same type tape, or
between opposite sides of the wound tape.
