A storage medium device has at least one head which includes a read head element and a write head element. The device has a deferrable element which changes a distance between the read head element and the write head element in a circumferential direction, a storage unit which stores a control value to be applied to the deferrable element in association with each target track for writing, and a deformation controller which acquires the control value corresponding to the target track for the writing from the storage unit, and applies the acquired control value to the deformable element.
