'Splicing'a damaged Video Tape
- This is purely a temporary measure and NOT a permanent solution. It may last indefinately, but, if it's just to get
important video footage off it then, do so and discard it. It's a lot cheaper to buy a new tape then to have your video repaired !
It's quite easy, but try not to handle the magnetic or(dull) side too much.
If you are uncertain about tackling it, watch the 'How to... DIY' series on 'Youtube' --'Splicing a music cassette'. Basically, the same applies.
To release the tape from the spools place the cassette on the table with the underside facing up. Release the spool sprocket spring lock through the bottom hole between the spools - only light pressure is needed. (You could tape something in there to give you two hands.) Now release the little flap spring lock at the side & lift the front flap to pull enough tape from either spool through either side of each guide roller to work comfortably. If the broken ends are inside the cassette then you will have to dismantle the cassette carefully and draw the ends over the guide rollers, replace the half and secure.
- Make sure both ends of the tape come through the tape transport path correctly before you attempt to 'splice'.
You will need:~
i. A4 card.
ii. Selotape wider than the V-tape
iii. Sharp knife
iv. 2 pieces of firm sponge slightly wider than the
selotape & about 20mm thick
v. Pair of sharp scissors
vi. Small x-head screwdriver(for cassette screws)if needed
vii. A clean piece of soft cloth
viii.Ruler & pencil
ix. Extra pair of hands-if needed
1. Tape a piece of A4 card to the tabletop. Using a
ruler draw a 'guide-line' accross the card through the
middle. Draw a centre line 50 mm long at 90 degs. Draw
two 40mm long lines either side of the centre at 13mm off
centre -this is the v-tape end overlap line. Draw another
two lines 70mm long 90 degs either side of the centre at
50mm off centre -this is the selotape guide line to give
a clearance of 37mm either side of the overlap.
Mark each line to denote it's function if required and
arrow the selotape lines so as not to be confused on
which side of the line to place the selotape-(arrows face
away)
2. Using scissors, cut away any damaged tape.
3. Place the cassette at the top of the card -with enough
tape spooled out from either side to work comfortably.
(Orientate the ends correctly with the 'dull' side down)
4. With the sponge stuck in the middle of a length of
selotape, secure one end with it's edge in line with the
'guide-line'. Position the v-tape in line with the guide
line & it's 'joint' end at the opposite overlap mark
drawn on the card.(Press on the sponge and then stick the
other end to the card)
5. Repeat for the other end in the same manner.
Looking from left to right you should have V-tape, selotape securing v-tape at right angles with sponge, 37mm clearance to the opposite end of the v-tape. The same repeated on the otherhalf of the centre line.
6. CHECK ALL IS CORRECT
7. Now, with both ends of the tape held in place, "splice"
through both layers at an angle of 45 deg: with a sharp
knife, remove cut ends. You should be left with a
neat cut at 45 deg. Align the tape if necessary with the
guide line. Measure and cut off a piece of selotape to
give a 10mm overlap eitherside past the point of the
angled cut-(approx: 35mm long) Carefully join the two
halves with the selotape centralized
8. Press down on the selotape using a clean cloth to smooth
out any air bubbles.
9. Release the v-tape carefully and trim off any overlapping
sellotape along the long edge with sicissors cutting a
fraction off the video-tape edge. This ensures no
sellotape glue will contaminate the video heads.
10.Remove the ratchet lock release if taped in place AFTER
Carefully windig-in the tape by rotating one of the
spools.
When released the lock will not allow rotation.
Retreve important Video footage and discard cassette.
Job done !
