Abstract
An actuator of a disc drive having a shock damping device includes an electro-magnet disposed on a cover of the disc drive, a magnetic material disposed on a load beam of the actuator, opposite to the electro-magnet, and a driving control portion controlling a driving of the electro-magnet by detecting an vibration of the load beam towards and away from an optical disc that is caused by an external shock. When the load beam is vibrated by the external vibration or shock to the disc drive, electricity is supplied to the electro-magnet, securing the load beam to the cover until the vibration ceases. Accordingly, even when there is external vibration or shock applied to the disc drive, possible damage to the disc or the actuator can be minimized or prevented.
