Abstract
A magnetic recording/reproduction apparatus using a magnetic head in sliding contact with a flexible magnetic disk for recording and reproduction, which has a negative pressure generating member disposed at the upstream side of the magnetic head and at the same side of the magnetic head with respect to the flexible magnetic disk, having an inclined surface inclined to be farther from the flexible magnetic disk towards the downstream side, and a positive pressure generating member disposed at the downstream side of the magnetic head and at the opposite side of the magnetic head with respect to the flexible magnetic disk, having an inclined surface inclined to be closer to the flexible magnetic disk towards the downstream side, the rotating flexible magnetic disk being attracted by the negative pressure and urged by the possible pressure to achieve stable sliding contact with the magnetic head.
