2-Speed Record/Playback gives you the option of recording on
a standard microcassette at either normal speed of 2.4cm/sec or half the
normal speed (1.2cm/sec), for extended recording or dictation sessions
On cassette decks, the unit automatically plays the reverse side upon
conclusion of the first side. Using the direction button, the user can
manually switch the playing side at any time. Continuous auto reverse
from side to side is featured in some models.
TAPE RECORDER SPEED
Normal Playback/Record speed = 1 7/8 inches per second or 4.8 centimeters
per second (CentiMeters)
1/2 Speed = 15/16 inches per second or 2.4 CM
1/4 Speed = 15/32 inches per second or 1.2 CM
is obvious advantage of slower tape speeds is the extended recording
time. For example, a C90 cassette recorded at the normal standard
cassette speed provides a total of 90 minutes of recording time -
45 minutes on each side of the cassette. Recording at 1/2 speed (2.4
CM) doubles the amount of recording time - 180 minutes total - 90
minutes per side. Recording at 1/4 speed (1.2 CM) provides 4 times
the normal speed record time - 360 minutes total - 180 minutes per
recorded in the 4-track format utilize the entire width of the tape
in one direction only. They are never turned over or recorded on the
other side. Thus a C90 cassette recorded in the 4-track format at
2.4 CM provides a total of 90 minutes recording time on one side of
the cassette only. At 1.2 CM the total recording time is 180 minutes
on one side only.
of slower tape speeds is a loss in audio quality. The speed at which
the tape passes the record/playback head is a large factor in determining
the quality of reproduction. The slower the tape speed, the poorer
the audio quality becomes. When extended record time per cassette
is necessary, a good compromise is 1/2 speed (2.4 CM). However if
the amount of recording time per cassette is not a factor, a much
better recording is produced at normal speed (4.8 CM).
BM-146 and BM-246 4-track recorders, frequently used in court reporting,
operate at 2.4 CM or 1.2 CM. Marantz PMD 1 and 2 track recorders may
be modified to operate at 2.4 CM. Transcription of tapes recorded
at these slower speeds requires a transcribing machine modified to
operate at the appropriate speed. Many transcribers and recorders
may be modified to operate at 2.4 CM and some at 1.2 CM. See modifications
for more details.
All microcassette transcribers and recorders currently being manufactured
operate at a tape speed of 2.4 CM or 1.2 CM which is selectable by
the operator. The MC60 microcassette provides a total of 60 minutes
recording time at the 2.4 CM tape speed - 30 minutes per side of the
cassette. At 1.2 CM the recording time is doubled - 120 minutes total
- 60 minutes per side. The rule governing quality of audio reproduction
in relation to tape speed applies to microcassettes as well as standard
cassettes. That is, the slower the tape speed, the poorer the audio
problem associated with microcassette machines concerns the dual speeds
found on these machines. A tape recorded at the 1.2 CM tape speed
will sound like "Donald Duck" (very fast) when played back
on a transcriber set for 2.4 CM tape speed. Conversely, a tape recorded
at 2.4 CM tape speed and played back on a transcriber set for 1.2
CM tape speed will sound very, very slow. The variable speed control
found on microcassette transcribers does not have enough range to
compensate for the two separate tape speeds. The solution is to match
the tape speed setting on the transcriber with that of the recording.
Used for cassette tape recording and playback. There are
single-well and dual-well cassette decks.

Use of tape recorders
An important use of tape recorders
is the recording of video. Video cassette recorders differ substantially
from audio recorders because of the use of a rotating magnetic head that
uses a helical scan of the tape medium. A helical scan is used to allow
for faster movement of the tape surface over the head.
