Cassette Tape Problems
The cassette tapes on which our books used to be recorded, which a small number of people are still using, can sometimes break, twist, or spill and ruin your reading enjoyment. Sometimes what appears to be a machine problem turns out to be a bad cassette. Here are a few tips for taking care of the cassettes and for correcting some problems you may have while listening.
Some of the procedures are delicate and may require help, so please don't attempt these if you don't think you can do it. Call us at (800) 342-3688.
- Clean Hands: It's a good idea to make sure that your hands
are clean when touching the cassettes and the cassette machine.
We also recommend that you keep the player and the tapes away
from direct sunlight and sources of heat, such as a sunny windowsill,
on top of a radiator, near the kitchen stove, and in the back
window of a car. Likewise, protect
the books and equipment from dust, dirt, food, moisture, and
severely cold weather.
- Inserting a cassette: When inserting a cassette into the machine, don't
touch the tape. Each cassette tape contains a felt "pressure pad" mounted
on a narrow copper spring under the tape. This pad is within the plastic
tape shell at the center of the thicker, open side of the cassette. The
pad opposes the player's play head, allowing the pressure of the head
to be applied firmly to the tape when it is being played. This is a delicate
area and should be treated with care. Handle the cassette by the edges
only, and don't touch the center part where the tape and tape guides are
- Loose on the spindle: Although you should receive the tapes fully rewound,
handling and travel through the mail can affect them and the tape can
become loose on the spindle. Before loading the cassette, check for any
slackness in the tape. When the cassette is in the machine, before you
play it we suggest that you press "Rewind" until the tape stops.
This winds up any tape sag and prevents uneven take-up and
jamming. All the tape is now on the left-hand
spool and all that's showing at the open side is the light-colored "leader." Doing
this also ensures that you start at the beginning of the book.
- Tape snarls: Tape snarls occur most often when the moving tape changes
speed or direction quickly. A small loop forms, and this can catch on
the player's drive mechanism. To lessen this risk, when playing a tape,
always press the "Stop" button before hitting "Rewind" or "Fast
Forward," and when going from "Rewind" or "Fast Forward" to "Play."
- Ridged tape: A common cause of a cassette not playing is that it is "ridged," meaning
that the tape has settled to one side of the spindle and binds against
the wall of the cassette case. This happens when the books are knocked
and vibrated as they are handled in the library and travel in the mail.
If a cassette won't play or starts to drag, try smacking the flat side
of the cassette on your hand or a table a few times, first one side then
the other. This should help the tape settle evenly onto the spool, making
it looser in the cassette case and allowing it to travel more smoothly.
Sometimes giving the cassette a gentle twist will also align the tape.
Another method is to fast-forward the tape for a couple of seconds and
then rewind it.
- Jammed tape: Another reason for a cassette jamming is that the tape
may be too tight. This can result from the tape not running evenly onto
the spools and this can cause difficulty in fast forward, rewind, and
play modes. If you experience this, try the "smacking" procedure
described above, or fast-forward and rewind the tape.
- Looped or twisted tape:Through use and handling,
the tape can move to the underside of the pressure pad. This allows the
tape to move but there will be no sound because the tape is not in contact
with the play head. You might think that there's something wrong with
your player, but in this instance that's not so. You'll probably need
someone to help you check this and to very carefully tease the tape back
to the correct position.
- Occasionally a tape won't move because it has looped
back on itself. You may not be able to see the loop, but
try manually winding the tape with a pencil until the loop
is visible and pull it out, and then carefully wind it
onto the spool.
- If a cassette is playing at the correct speed but is
unintelligible, it may be that the tape has twisted over
on itself and is playing the wrong side up. Often you can
manually spool the tape, find the twist, and straighten
- If the tape you're playing speeds up and then sounds
garbled, stop the player immediately. The tape has probably
become snarled in the drive mechanism. Carefully remove
the cassette and manually spool the tape back into the
- Occasionally a tape won't move because it has looped back on itself. You may not be able to see the loop, but try manually winding the tape with a pencil until the loop is visible and pull it out, and then carefully wind it onto the spool.
- Remember to switch off the cassette machine after the tape has finished playing. The machine has an automatic cut-off switch when the tape stops, but any unnecessary tension could stretch and distort the tape.
