A carriage of a head positioning assembly is disposed along an edge of a magnetic disc so as not to come in contact with the magnetic disc, whereby the length of the winding bobbin of the voice coil can be elongated, so that a driving force generated in the elongated winding bobbin causes a magnetic read and write head to rapidly move to a position over an objective track on the magnetic disc.
