摘要： PROBLEM TO BE SOLVED: To reduce vibration of a hard disk drive in regard to a disk drive device. SOLUTION: The hard disk drive 100 includes: an upper dynamic pressure plate 34 on an upper side of a magnetic recording disk 200; and a lower dynamic pressure plate 32 on a lower side of the magnetic recording disk 200. When the magnetic recording disk 200 rotates, a dynamic pressure is produced in an air between the upper dynamic pressure plate 34 and the magnetic recording disk 200. A dynamic pressure is also produced in the air between the lower dynamic pressure plate 32 and the magnetic recording disk 200. By the dynamic pressures, the magnetic recording disk 200 is supported in a thrust direction. A recording/reproducing head records data on the magnetic recording disk 200, and reads the data from the magnetic recording disk 200. The upper dynamic pressure plate 34 is disposed on the same side as the recording/reproducing head when viewed from the magnetic recording disk 200, in a manner to avoid a swing area of the recording/reproducing head.
