UA68792U - Magnetic recording reading device - Google Patents

Abstract

A magnetic recording/reading device comprises a record block connected to a record head, an executive unit, three single-slot reading heads, two of them are arranged symmetrically relative to the magnetic medium axis at the distance equal to a half of record head gap width and a half of its pole width and at the distance equal to a half of record head pole thickness relative to third single-slot reading head arranged on the magnetic medium axis, along the magnetic medium axis. The single-slot reading heads are connected to series connected resonance amplifiers, phase detectors and threshold switches, which outputs are connected through NOT and AND logical elements to a decoder. The eighth and ninth single-slot reading heads are used, those are arranged symmetrically relative to the magnetic medium axis at the distance equal to a half of record head gap width and a half of its pole width, and are shifted along the magnetic medium axis at the distance equal to a half of record head pole thickness relative the central single-slot record head arranged on the magnetic medium axis. The windings of the eighth and ninth single-slot reading heads and windings of single-slot reading heads arranged symmetrically relative to the main single-slot reading head along the magnetic medium axis are in-series connected.
