<p>Arrangement of magnetic recording and/or readout heads for disc memories, these discs comprising on their surfaces a certain number of concentric magnetic zones each constituted by a particular number of circular tracks. In one embodiment of the invention, a hybrid arrangement is provided, that is to say with several heads, which are offset radially but each having a limited radial movement corresponding to the width of a single magnetic zone. In another embodiment of the invention, the support of the pads is actuated through an articulated parallelogram system.</p> |
