ABSTRACT:
A magnetic recording and/or reproducing device for recording information on a disc-like magnetic recording medium and/or reproducing the information from it, said magnetic recording and/or reproducing device having a pair of magnetic head members each composed of a magnetic head chip and a slide pad for slidably holding the disc-like magnetic recording medium at its both surfaces between the pair of magnetic head members under a predetermined contact pressure, wherein the slide pad is so disposed as to surround the magnetic head chip and the top portion of the magnetic head chip is so disposed as to protrude by a predetermined amount from a sliding contact surface between the slide pad and the disc-like magnetic recording medium. It makes possible by the magnetic recording and/or reproducing device of the above described type to obtain such a desirable state in which the disc-like magnetic recording medium can be steadily held in contact with the magnetic head chips, since the slide pads act primarily to minimize the warp of the disc-like magnetic recording medium and also the deformation of the disc-like magnetic recording medium which would result from a deviation in position of one or both of the magnetic head members relative to the disc-like magnetic recording medium.
