TH17438EX - Magnetic contact disc file with resistive magnetic reading recognition sensor. - Google Patents

Abstract

The contactless magnetically recorded hard disk file uses a resistive magnetic (MR) sensing machine for reading data recorded on the disc. The performance of the disc file is enhanced by combining a pathway for minimizing the effect of the waveform modulation. Wave modulation was determined by the variability of the temperature-sensitive and temperature-raised MR senses by the plate, where the temperature variation is directly related to the variation in the head-plate spacing caused by The oscillation of the disc surface may be integrated into the disc file read processing circuit to eliminate the wave mixing. The MR receiver may be designed to operate at the selected parameter to optimize the modulation effect. Modulating the slightest wave signal And the carrier portion in contact with the plate surface may be selected so that it is less than the plate's wavy period, so that it follows more closely than the topographic of the plate surface.
