The device comprises a carriage mobile radially relative to the disk, and on which lower and upper opposing magnetic heads are mounted, each for recording and/or reading a corresponding disk face. The upper magnetic head is resiliently mounted at the end of an arm pivoted to the carriage and is urged against the disk with a predetermined load determined by a spring. A flexible joint enables it to rotate in all directions about a central support. The lower magnetic head is connected to the carriage by means of a pair of parallel leaf springs which enable it to move along an axis normal to the plane of the disk without rotation, whereby both heads maintain good contact regardless of the height of the nominal plane of the disk.
