Combination perpendicular record and reproduce head having an auxiliary pole recessed from an air bearing surface and spaced from one of a pair of reproducing element sheilds

A magnetic recording apparatus, comprising:

• a two-layered medium comprising a soft magnetic backing layer and a perpendicular recording layer;
• and
• a recording head comprising a main magnetic pole, an auxiliary magnetic pole provided to face the main magnetic pole with a gap therebetween and recessed from an air-bearing surface against said medium of the main magnetic pole, an exciting coil, a reproducing element, a pair of reproducing shields sandwiching the reproducing element, one of the reproducing shields adjacent to the auxiliary magnetic pole being positioned apart from the auxiliary magnetic pole by such a distance that a magnetic field generated in recording under the auxiliary magnetic pole becomes larger than a magnetic field under the reproducing shield.

A magnetic recording apparatus, comprising:

• a two-layered medium comprising a soft magnetic backing layer and a perpendicular recording layer, the perpendicular recording layer showing a magnetization curve in which a point at which irreversible magnetic reversal begins to take place resides in the second quadrant and an absolute value of a magnetic field corresponding to an intersection between a tangential line of the magnetization curve drawn from a point of coercive force in a region where an applied magnetic field is negative and a straight line drawn in a horizontal direction from a point of residual magnetization is greater than a magnetic field generated in recording under the auxiliary magnetic pole;
• and
• a recording head comprising a main magnetic pole, an auxiliary magnetic pole provided to face the main magnetic pole with a gap therebetween and recessed from an air-bearing surface against said medium of the main magnetic pole, and exciting coil, a reproducing element, a pair of reproducing shields sandwiching the reproducing element, one of the reproducing shields adjacent to the auxiliary magnetic pole being positioned apart from the auxiliary magnetic pole by such a distance that a magnetic field generated in recording under the auxiliary magnetic pole becomes larger than a magnetic field under the reproducing shield.
