Splicing the Tape

Be sure the control lever is in the STOP position.

A

l.llace an empty reel on the 9 right reel tahle and a full
reel on the 9 left reel table.

2, Use reel clamps to retain reels on the DIiCK.

3. Holding the end of the tape straight and flat between the
left and right hand, place in evenly in the slot of the head
housing.

4.Secure the end of the tape to the empty reel huh. (Do
not secure it with a reel clamp.)

S. Rotate the empty reel counterclockwise to remove any
slaek in the tape.

Should your tape be broken or should you desire to edit
a tape. use the procedures outlined below

Scissors: Completely demagnetize the scrssnrs by use of the
Head or Bulk demagnetiter~ Use of a magnetized scissors
will result in a Click at the spliced area.

Splicing tape: Use only a commercial splicing tape, Never
use Celophane (Scotch) tape as the adhesive will spread and
contaminate your recording heads.

Methm of splicing: Overlap the ends to be spliced by
approximately '5. inch. align them carefully then out
through the center of the overlapped area at a 60" angle,
The ends of the slanted cut tape are then huttcd together

and the splicing tape rubbed briskly with your fingernails or
any hard smooth object. Next trim off any excess splicing
tape, cut slightly into the tape on both edges at the spliced
area. (See illustration).

General Information and Precautions at Recording

The tape

The length of a recording tape as well as tlte recording
time. is determined by the reel diameter and the thickness
of the base material.

The use of a | 0| l/: mil base tape is recommended for 4
track hiin fidelity recording. Polyester base tape is preferred
for use in humid or extremely dry areas.

Three recording speeds are commonly used. 3%, and 7%
inches per second

7% ips is commonly used for home high fidelity
recording. Generally speaking, the higher the recording

speed. the better the fidelity. However. due to the extieme-
ly high quality of the TEAC tape decks. recordings of
excellent quality can be made at the lower speeds. This
provides maximum tape economy and extended playing
time.

The recording time indicated in the chart below is for one
single pass of the tape, therefore the total recording time
will either two or four times that indicated. depending upon
the method of recording.

Good quality tape wound on correct reel

U:

Tape condition can be judged by the appearance

when wound on the reel and viewed from the side.

1) is it neatly wound? 2) ls there steps or irregularities in
the winding? 3) Is the color of base uniform as seen from
the side? 4) is the tape edge smooth?

V

k/

Spots seen on the edge indicate drop out (skipping of
sound)

b-

Creases extending from the center positively indicate uneven
stretching. This is caused by differences in temperature and
humidity.

V

k/

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.

Selecting the tape and reel

For recording, new tape is not necessarily needed as long
as it is of good quality as 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. is

i

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.

Judging tape condition by how it travels.

Head

Tapes which snake up and down between the guides and
over the heads will inevitably lead to level fluctuations and
azimuth misalignment.
