MAGNETIC FIELD GENERATOR, A METHOD FOR CONTROLLING THE MAGNETIC FIELD GENERATOR AND A DEVICE FOR PROCESSING THE MAGNETIC RECORDING MEDIUM Russian patent published in 2018 - IPC G11B5/09 

FIELD: physics.

SUBSTANCE: group of inventions refers to a magnetic data reader recorded on a magnetic recording medium. Device for a magnetic field generating comprises a magnetic field generation unit that comprises a resonance part in which an inductive element and a capacitor are connected, and which charges the capacitor and discharges the accumulated charge, thereby causing the alternating current flow between the inductive element and the capacitor and generating the magnetic field during resonance; a current direction tracking unit that tracks the current direction flowing in the inductive element of the magnetic field generation unit, and a determination unit that controls the charging time at the magnetic field generation unit in accordance with the current direction flowing in the inductive element, while the time point is set by tracking the current direction tracking unit.

EFFECT: increase in the efficiency of generation of a distorting magnetic field.
