Abstract
On a head slider 203a, a read/write head 20 for reading and/or writing information on a disk being a rotatable recording medium is mounted. The head slider 203a comprises: a head slider body; a dynamic-pressure generating part 2a (2b) for generating a dynamic pressure, the dynamic-pressure generating part being formed on a surface of the head slider body facing the disk; and a negative-pressure generating part 81a (81b) for generating a negative pressure, the negative-pressure generating part being provided on a plane of the head slider body facing the disk and in the rear of a central portion of the head slider body in a rotating direction of the disk. Thus, it is possible to provide a head slider having a small yaw-angle dependence, and a read/write apparatus, which has the head slider and which is capable of improving the recording density thereof.
