Apparatus for performing high density digital magnetic recording of a binary code string using isotropic/perpendicular media comprises a generator for generating a current, and a magnetic head (405) including a winding (404) coupled to the generator for generating a magnetic field having a polarity corresponding to the polarity of the current coupled to the winding (404). The magnetic head (405) and the media are inductively coupled as the head and the media move longitudinally with respect to one another. Control circuitry switches the current off in the winding in response to detecting a one in the binary code string thereby to cause the whole write field of the head to be imprinted on the media leaving a horseshoe type magnetic remanent thereon. |
