Magnetic tape apparatus for recording and reproducing of signals
Abstract
It is known by a matrix head large amounts of digital data at extremely high bit rate, ie in a very short time to record on a magnetic tape (T). Thanks to the matrix head (RH), which allows the recording of a large number of parallel tracks without turf, with the fixed head (RH) the same recording density can be achieved as with helical track recording. The invention has for its object to provide a simple way a recording and playback capabilities for a magnetic tape device (MP). The device according to the invention is intended for the storage of very large amounts of sound signals, which are recorded as a digital signal after data reduction. The device is to be used as a portable playback device and allow for dimensions that are only slightly larger than a commercially available magnetic tape cassette, access to pieces of music that correspond to the content of about 200 CDs, for example, without tape change.
