Low wear rate magnetic head slider with high recording density

A magnetic head comprising:

• a magnetic recording/reproducing element for performing recording and reproduction with respect to a magnetic disk medium;
• a contact magnetic head slider on which said magnetic recording/reproducing element is mounted, said magnetic head slider having a press load of not more than 1 gf, and a mass of not less than 2 mg;
• and
• a support mechanism for supporting said magnetic head slider.

A magnetic disk device comprising:

• a magnetic head for performing recording and reproduction with respect to a magnetic disk medium;
• and driving means for driving said magnetic head,
• wherein said magnetic head comprises:
