Abstract: A fluid dynamic bearing is constructed to support stably a rotating body to which a non-uniform force is applied, and a hard disk drive (HDD) employing the fluid dynamic bearing is provided. The fluid dynamic bearing includes a journal bearing part supporting a rotary shaft in a radial direction of the rotary shaft, a thrust part formed at one end of the rotary shaft, a thrust bearing part facing the thrust part and supporting the rotary shaft in a longitudinal direction of the rotary shaft, and a plurality of grooves formed on a surface of the thrust bearing part and/or the thrust part. The plurality of grooves include a first groove group including a plurality of grooves having the same shape and arrangement, and a second groove group adjacent to the first groove group and including at least one groove asymmetric with respect to the grooves of the first groove group.

Abstract: An HDD(Hard Disc Drive) and a head unlatch control method of the HDD are provided to prevent an existing problem in which unlatch failure is continuously generated when it is impossible to read a servo sector because a particle or a haze is generated in a disc area. A head(21) records data on a disk(10) or reproduces the recorded data. The head(21) is mounted in an actuator. A VCM(Voice Coil Motor) driving unit(87) supplies a current to a VCM which drives the actuator. A controller(90) sets an unlatch speed in which the head(21) is moved from a parking area to a data area in a radius direction of the disk(10) as a predetermined reference speed, and performs the unlatch of the head(21) on the basis of the unlatch speed. When the unlatch of the head(21) fails, the controller(90) provides a control signal to the VCM driving unit(87) to change the unlatch speed and perform the unlatch of the head(21) on the basis of the changed unlatch speed again.
