ABSTRACT:
A disk drive has at least one disk for storing data and at least one transducer for reading or writing data to or from the disk. The transducer is attached to an actuator which positions the transducer with respect to the disk. The actuator includes a controllable motor which is used to move the actuator and the transducer attached thereto. The disk drive also includes a ramp for off loading the transducer or for parking the transducer off of the surface of the disk. The disk drive includes a combination shock absorber and gasket that has locking tabs to keep the combination shock absorber and gasket in place during a shock or impact loading event. The combination shock absorber and gasket also can be provided with additional extensions to lessen shocks caused by flat drops. Elastomeric blocks or pads can be provided on the cover and the base to lessen shocks caused by flat drops. The drive can also have rotatable elastomeric blocks that can rotate to a position above the disk drive to lessen shocks resulting from flat drops. The drive also is provided with a shock sensor which provides visual evidence that the drive has undergone a shock of a predetermined threshold. Another shock absorbing system uses a shroud around the connector on the disk drive.
