Patent ID: 8295009

Claim:
A magnetic recording apparatus comprising: a magnetic recording medium; a magnetic writing head including, a main magnetic pole, a coil to generate an am ere magnetic field to magnetize the main magnetic pole to cause the magnetized main magnetic pole to generate a magnetic field, a laminated body including: a first magnetic layer having a coercivity lower than the magnetic field applied by the main magnetic pole, a second magnetic layer having a coercivity lower than the magnetic field applied by the main magnetic pole, and a shield, wherein the laminated body is sandwiched between the shield and the main magnetic pole, and each of the main magnetic pole and the shield have a back gap portion, a moving mechanism configured to allow relative movement between the magnetic recording medium and the magnetic writing head which are opposed to each other with a spacing therebetween or in contact with each other; a controller configured to position the magnetic writing head at a prescribed recording position of the magnetic recording medium; and a signal processing unit configured to perform writing of a signal on the magnetic recording medium by using the magnetic writing head.
