摘要： A magnetic disk storage device having a magnetic shield for shielding a magnetic servo-head from noise generated by an adjacent data-head during a write operation when both magnetic heads are arranged back-to-back in a space between two magnetic disks stacked co-axially. The shield plate is secured to an inner surface of a base portion of a housing of the device, thus avoiding an increase in the weight and moment of inertia of moving members of a head positioner.
