Micro miniature hard disk drive

A head disk assembly (HDA) for magnetically recording data, comprising:

• a spindle motor connected to provide rotation of a fixed hard disk media and having a back electro-motive force (EMF) output that produces a voltage when power to the spindle motor is shut off;
• an actuator assembly connected to provide random access of a magnetic read/write head across a surface of said hard disk media and including a pair of read/write heads attached to an actuator with a pair of suspensions, an actuator coil attached to said actuator for repulsing and attracting a lower magnetic plate, an upper magnetic plate and a ferrous member on a latch arm attached to said actuator, wherein said actuator coil, lower magnetic plate and upper magnetic plate form a first voice coil motor (VCM) that provides for moving the actuator assembly with said voltage from said EMF output;
• and
• an active actuator latch assembly positioned proximate to the actuator assembly and including a magnet on an arm mounted on a pivot shaft and held in one extreme position of rotation by a spring, a second voice coil motor (VCM) connected to rotate said arm against said spring, a pair of magnetic plates within magnetic reach of said VCM, and a pair of limit arms to limit the range of rotation of said arm on said pivot, wherein the actuator assembly may be positively latched in a parked position by rotating said arm such that said magnet comes in contact with said ferrous member on the actuator assembly in a parked position after the power of said spindle motor is shut off.
