Hard disk drive having disk locking apparatus utilizing offset dummy slider/suspension arrangement

A hard disk drive comprising:

• a disk storing data, having a parking zone and a data zone at a first side surface thereof;
• a spindle motor installed on a base plate, and rotating the disk;
• and
• an actuator pivotally installed on the base plate and having a first arm disposed at the first side surface of the disk and a second arm disposed at a second side surface of the disk;
• a suspension having a predetermined elastic force and installed at the first arm, and a slider with a mounted magnetic head recording and reproducing data installed at an end portion of the suspension to be elastically biased toward the disk by the suspension;
• and
• a disk locking apparatus installed, at the second arm, to be disposed at a position at an outer side of the slider in a radical direction, and locking the disk to prevent rotation by contacting the second side surface of the disk when the disk stops rotating.

A hard disk drive, comprising:

• at least two rotary disks storing data and having a parking zone and a data zone at an odd number of surfaces thereof;
• an actuator having arms disposed at each surface of the disks;
• suspensions installed at each arm and elastically biased toward each surface of the disks;
• data sliders recording and reproducing data installed at an end portion of each suspension biased toward the zoned surfaces of the disks;
• and
• a disk locking apparatus installed at an end portion of each suspension biased toward non-zoned surfaces of the disks and locking the disks when stopped by contacting the non-zoned surfaces of the stopped disks, wherein the disk locking apparatus is disposed at a position at an outer side of the data sliders in a radial direction, the data sliders being disposed at the zoned surfaces of the disk.

• and
• a disk locking apparatus installed, at the second arm, to be disposed at a vertically different position of the slider with the mounted magnetic recording and reproducing head, and locking the disk to prevent rotation by contacting the second side surface of the disk when the disk stops rotating.
