Microcassette (Steno-cassette) to a tape
recorder Grundig DeJUR Execumate Stenorette. On this
tape you can record one track for 30 minutes at a speed
of 2.38 cm / sec. The cartridge design does not allow to
curl up and make a second track record, but it has a
built-in tape counter. The counter has a complex
structure, it uses a few gears and worm screw. Almost
all body parts and plastic tapes. Dimensions 65 x 45 x
10 mm, Weight 23 ã. gears and screw visible on the
enlarged photographs. Also in the cassette has built-in
contacts, which are likely to trigger hitchhiking. They
are closed with metallic coating on the tape at the end
of winding. Contact withdrawn on the underside of the
tape, and when it is inserted, pressed to the
appropriate contacts of the recorder. In my recorder
when playing hitchhiking does not work, perhaps it is
defective. However, when writing, when the tape ends,
the speaker produces a loud sound of high tone. May
serve as contacts for the inclusion of the warning
Information from Wikipedia: (Steno-Cassette) - format a
tape for my tape recorder magnetic recording of sound,
proposed by Grundig in 1971 (sales in 1973). In the
1970's and early 1980's steno-cassette spread to Germany
and became the subject of a national standard DIN 32750
(1985). In 2008, the tapes and the recorders of this
format continue to be sold under the brand Grundig
Stenorette and positioned as a high-quality and
expensive solution "for business" (the cost of the
simplest recorders from 200 euros). In 1995, the same
Grundig brought to market, in addition to the family
Stenorette, a family of microcassette recorders, and a
catalog company in 2008 represented the family for three
recorders - two analog and digital.
