ABSTRACT:
A magnetic disk driving device comprising a flexible disk-shaped magnetic recording medium; a first motor for rotating the magnetic recording medium; first and second head supporting members for supporting first and second magnetic heads, respectively, the first and second head supporting members being formed with recesses from which the first and second magnetic heads project toward the magnetic recording medium; a second motor for moving the magnetic heads; and first and second arms extending along opposite surfaces of the magnetic recording medium, the first and second arms having respective free ends where the first and second head supporting members are mounted and having respective base ends where a rotating shaft of the second motor is directly fixed; wherein the first and second arms are adapted to be rocked within a predetermined rocking angle defined in such a manner that when the first magnetic head supported by the first head supporting member is located in opposition to an outermost recording track of the magnetic recording medium, the second magnetic head supported by the second head supporting member comes to a position opposed to an innermost recording track of the magnetic recording medium.
