Magnetic transducer head

Abstract

Abstract A magnetic transducer head comprises a first magnetic pole (10) for recording and / or reproducing signal on a travelling magnetic recording medium (11), formed of a thin film of magnetic material facing to the travelling magnetic recording medium at one end of the thin film and having a predetermined width corresponding to a recording track width on the magnetic recording medium; a coil (17) coupled to the first magnetic pole for recording and or reproducing signal on the travelling magnetic recording medium; second and third magnetic poles (18 a, 18 b) for erasing magnetic record at peripheral portions of the recording track formed of thin films of magnetic material each facing to the travelling magnetic recording medium at one end of the thin film, the second and third magnetic poles provided remote from the first pole with a predetermined distance along a travelling direction of the magnetic recording medium; a coil (21) coupled to the second and third magnetic poles for erasing magnetic record; and a coil (40) coupled to the first magnetic pole to compensate an erasing magnetic field from the second and third magnetic poles in the first magnetic pole.
