There are provided a hydrodynamic bearing assembly and a spindle motor including the same. The hydrodynamic bearing assembly includes: a sleeve including a shaft hole to have a shaft rotatably installed therein; and a cover member covering the shaft hole at a lower portion of the shaft hole in an axial direction, wherein an inner surface of the sleeve is provided with depression parts depressed in an outer diameter direction between upper and lower portions of the sleeve and portions in which radial bearings are formed, such that the portions in which the radial bearings are formed are provided with bearing closure adhesion parts allowing the portions in which the radial bearings are formed to be closer to the shaft than portions other than the portions in which the radial bearings are formed.

Disclosed is a fishbone diffraction-type light modulator. In the fishbone diffraction-type light modulator, a lower micromirror is provided on a silicone substrate, and an upper micromirror is spaced apart from the silicone substrate and has a plurality of openings through both sides thereof. The upper micromirror and the lower micromirror deposited on the silicone substrate form pixels.

Disclosed herein is an inertial sensor, including: a membrane; a mass body disposed under the membrane; a sensing unit formed on the membrane and including a piezoelectric body; and a spring constant control unit formed to be spaced apart from the sensing unit and including a piezoelectric body. According to the preferred embodiment of the present invention, the DC acceleration (in particular, gravity acceleration) can be measured by using the change in the spring constant without changing the structure of the inertial sensor including the piezoelectric material of the prior art.
