ABSTRACT:
A magnetic disk apparatus has a rail support which supports guide rails for guiding a carriage on which heads are mounted. The rail support is positioned outside a magnet of a voice coil motor and mounted on a frame. The guide rails are disposed so as to extend across a cavity in the rail support and have their opposite end portions attached to the rail support. The guide rails do not vibrate even if the voice coil motor receives a reaction during head seeking, whereby the head positioning accuracy can be improved and the storage capacity can be increased. The rigidity of the guide rails is increased by supporting the opposite ends of the guide rails. This structure and a coaxial arrangement of a motor coil allow the overall length of the carriage and, hence, the overall size of the apparatus to be reduced.
