ABSTRACT:
The two-sided magnetic recording and reproduction device according to the present invention is very simple in structure in which a single negative pressure generating type stabilizing plate is used to achieve good contact of two magnetic heads with the front and backside of a magnetic disc, whereby position adjustment and assembly work of the individual members can be simplified to achieve a reduction in cost, the frictional resistance of the stabilizing plate to the magnetic disc can be reduced to reduce the driving torque, and abrasion to the magnetic disc and the magnetic heads can be suppressed. Furthermore, since the upper and lower heads are inclined to the inside and outside with respect to the magnetic disc, or, the surface of the stabilizing plate opposing the magnetic disc is inclined in the direction to the inner and outer peripheral sides, the gaps of the upper and lower magnetic heads are caused over their entire widths to come in sliding contact, thereby achieving a very good and stable head contact.
In addition, since there is provided supporting means for elastically supporting one of the upper and lower magnetic heads, a good contact of the magnetic heads following the magnetic disc is achieved, thereby enabling stable recording and reproduction.
