摘要： A hard disk drive with an actuator arm assembly that is coupled to a head and includes a voice coil motor. The drive also includes a drive circuit that provides a drive current to the voice coil motor to move the actuator arm assembly into contact with a magnet. The drive circuit limits an amplitude, and/or changes the pulse width, of the drive current as the actuator arm assembly approaches the magnet. Limiting the amplitude and/or changing the pulse widths reduces any audible noise associated with retracting the heads.

摘要： A disk hard disk drive that includes a spindle motor and an actuator arm coupled to a base plate. A plurality of disks are coupled to the spindle motor and a plurality of heads are coupled to the actuator arm and the disks. The drive also includes a cover attached to the base plate. The cover and base plate enclose a hard disk area that has a horizontal center line. The hard disk area includes a volume of air above the horizontal center line that is equal to a volume of air below the horizontal center line. The air space within the hard disk area is equal and symmetrical in a vertical direction. Such an arrangement reduces track mis-registration when servo is copied from a disk surface to the other surfaces of the disks in the drive.

摘要： A hard disk drive that includes a voice coil motor controlled by a servo circuit. The servo circuit provides a sinusoidal driving signal that has two different harmonic frequencies. The dual harmonic waveform creates a voice coil motor jerk profile (derivative of acceleration) that is continuous. The continuous jerk profile reduces vibration and seek time of the drive.

摘要： Apparatus and method of controlling the on-track position of an actuator in a hard disk drive to be held on a predetermined position of a track. The apparatus includes a voice coil motor (VCM) driving unit, a position detecting unit, and a controller. The voice coil motor (VCM) driving unit applies a predetermined current to drive a voice coil motor (VCM). The position detecting unit reads data read by a head to detect a position of the actuator. The controller disables the voice coil motor (VCM) driving unit after unlatching the actuator, and enables the voice coil motor (VCM) driving unit if the position detecting unit detects that the actuator is positioned on a predetermined track and bringing the actuator on-track depending on the output of the position detecting unit. The method includes the steps of unlatching the actuator, disabling a voice coil motor (VCM) driving unit, determining whether the actuator stops on a predetermined track, and enabling the voice coil motor (VCM) driving unit if the actuator stops on a predetermined track, to bring the actuator on-track. Thus, the voice coil motor (VCM) driving unit is disabled after unlatch, minimizing external disturbance due to offset of circuits or devices, such as the voice coil motor (VCM) driving unit, an operational amplifier (OP-AMP) and one or more passive elements of the apparatus.
