An optical disk drive includes a light source, a light focusing element, a light-focusing-element moving mechanism, a detecting unit, a holding unit, and first and second control units. The light focusing element arranged so as to be opposed to a disk on which a signal is recordable is capable of focusing light emitted from the light source as near-field light on the disk. The detecting unit detects a state where the moving mechanism approaches the light focusing element to the disk such that the light is focused as near-field light on the disk and outputs a detection signal upon detection. The holding unit holds a voltage applied to the mechanism in response to the detection signal and is capable of releasing the held voltage. The first and second control units perform first and second control operations to control the distance between the light focusing element and the disk.

A suspension assembly of an actuator of a hard disk drive prevents collisions with a data storage disk of the drive. The suspension assembly includes a load beam, a bracket having a rear end at which the bracket is coupled to the load beam and a flexure, a slider that is attached to the bracket and carries the read / write head of the hard disk drive, and a limiting mechanism capable of selectively attaching and detaching a respective portion of the bracket to and from the load beam during operation. The load beam has a dimple projecting toward the bracket and which normally contacts a first surface of the bracket. The slider is attached to a second surface of the bracket opposite the first surface. The limiting mechanism attaches a portion of the bracket bearing the slider to the load beam when the read / write head is unloaded from the disk. Therefore, the wobbling of the slider is suppressed during the unloading operation. On the other hand, the portion of the bracket bearing the slider is detached from the load beam during a read / write operation to allow the slider to pitch and roll more freely about the dimple.

According to the invention, in a semiconductor device that needs a refresh operation for storing data, data of memory cells selected in response to a row address is read to main amplifiers through bit line pairs, sense amplifiers and data line pairs in a page-mode read operation.

Also, in a page-mode write operation, while writing externally supplied input data in the main amplifiers, the memory cells can be precharged.

In a conventional method for preventing a collision between a lens and an optical disc which uses a control system similar to the servo control of the optical disc, it is feared that, when there is no need to apply the servo, the collision prevention method may not perform its function satisfactorily.
