Read and translate the following text from English into Russian using a dictionary.
COMPACT DISC
The invention of the compact disc (CD) was the result of research carried out on the
video disc by the Dutch electronics company Philips NV. Under a joint licensing
agreement by Philips and the Japanese company Sony, the CD was first developed in
1979. A process of digital recording is used, rather than the analogue recording process.
The signal is coded in binary form, using series 0 and 1. The sound is reproduced by a
laser beam. The compact disc has a diametre of 5 inches and can hold 75 minutes of music
or sound on one side.
The CD was first marketed in 1983, and by 1991 had outstripped both traditional
forms of recorded music - records and tapes - in terms of unit sales and values. In the
space of a few years, the CD has achieved incredible success, and its applications are
many and varied. In 1984 Philips and Matsushita brought out the prototypes of decoders
that enabled fixed images, which had been stored on CDs alongside an audio signal, to be
viewed on television. In 1985 the extensive storage capacity of CDs was applied to
computers. CD players now have the capability of running a disc at twice the normal
speed, which makes it possible to record an hour-long disc onto a cassette in just 30
minutes.
