sECTION 5 EDITING
Once a tape has been recorded, it may be necessary to re-
arrange the order of some takes, splice two different reels of
tape together, or, to add leader tape between takes on a
given tape. All these operations are considered to be editing.
To edit a tape, one should have the following materials
available:
1. A splicing block. This is usually made of aluminum, with a
groove to hold the tape, and one or more grooves cut
across the length of the block to guide the cutter.
2. A sharp, non-magnetic single-edged razor blade. To be
sure the blade has no residual magnetism, it can be
demagnetized in much the same way that the head
assembly is demagnetized (Section 7). Be sure to hold the
blade securely, however, since a demagnetizer may pull
strongly on the blade.
NOTE: We do not recommend using scizzors. Also, a
magnetized razor blade will cause an audible ` сек” or
“pop” at the point of the splice.
3. A sharp white or yellow grease pencil to mark the intend-
ed splice point on the back of the tape.
4. А roll of 1/2" wide (1.3 ст) splicing tape. Splicing tape is
specially manufactured for joining magnetic tape; it is
thin, and has an adhesive that will adhere to the tape
backing, yet not seep out of the splice under the typical
pressures and temperatures encountered.
CAUTION: Never use conventional cellophane tape or
packaging tapes for splicing. Some of the adhesive on
such tapes may ultimately contaminate the recording
tape, and may leave deposits on the tape heads and
guides.
5. A supply of plastic or paper leader tape; plastic is
stronger, but paper is easier to write upon with a pen or
pencil, and is thus handy for making notes.
HIGH SPEED SEARCHING FOR AN EDIT POINT
If one is searching for the end of a take, or the beginning of
another take, the search can be done in fast forward or re-
wind mode.
1. Turn down the monitor amplifier volume most of the way.
2. Press the A-2 REWIND or F. FWD button, and press the
CUE lever toward the head assembly so that the tape
lightly rests on the record/play head.
3. A high-pitched squeal will be heard during the program,
with a moment of silence at the end of the program; at
that point, hit the STOP button. Since the tape will pro-
bably overshoot the intended edit point, it may be nec-
essary to use the opposite fast wind mode momentarily,
then press STOP again.
4. For more precise location of the edit point, rewind slightly,
then use PLAY to find the exact edit point and press
STOP. (NOTE: Return the monitor volume to normal once
fast-winding in cue mode has been completed).
SPILLING AN UNWANTED SEGMENT OF THE
TAPE.
It may be desirable to “dump” a portion of the tape, such as
a long pause or an unwanted segment of the program. First
locate the beginning of the segment as indicaled in the
previous procedure.
1. Press down the head gate so it retracts and latches down.
Тһе edit point on the tape will be in contact with the
record/play head (the head nearest to the takeup reel).
Mark the back of the tape at the edit point with a grease
pencil, then allow some slack and cut the tape.
2. Press the EDIT button to release the takeup reel tension
(the reel brakes are still engaged).
3. То spill "unwanted" tape and find the next edit point,
press the PLAY button. When the desired second edit
point is heard, press STOP.
4. Splice the ends of tape from the two reels together, insert-
ing a piece of leader tape between takes if desired.
5. Disengage the EDIT button and resume normal operation
by taking up any slack so the tension arm sensors are
actuated.
