Abstract

A hard disk drive, its use and production are described. A read / write disk stores digital data. A spindle motor supports the read / write disk for controlled rotation thereof. A head arrangement moves to selectively access the read / write disk in a data access mode and moves to a parked position. A dedicated input is receives a first sensor related input signal. A processing arrangement executes the data access mode by cooperatively controlling the spindle motor and the head arrangement, monitoring the sensor related input signal for a predetermined characteristic thereof, and responsive to detection of the characteristic, at least moves the head arrangement to the parked position. A hard disk drive multi-sensor group, monitoring technique and interface are described.

Description

Background technique [0001] Hard disk drives are known to be susceptible to mechanical shocks, especially in data access modes where the head device accesses the rotatable storage disk. Consequently, dropping a hard drive while the hard drive is undergoing disk access often results in loss of data, or even catastrophic failure of the drive. In this regard, hard drives are generally substantially more resistant to mechanical shock when the head assembly of the hard drive is in the parked position. In an attempt to avoid mechanical shock related failures during disk access, one prior art approach relied on moving the head assembly to a parked position in anticipation of a mechanical shock. A specific example of this approach is provided in US Patent No. Re. 35,269 to Comerford. [0002] Comerford's patent discloses a protective reflex system that uses a three-axis accelerometer arrangement. The output from the three axes of the accelerometer is processed to identify a zero or...
