ABSTRACT:
A floating-type optical head includes a floating slider for floating over a medium as a result of an airflow generated on the recording surface of the medium, an optical device including at least a light condensing unit for condensing a light beam, and a support unit to which the optical device is attached. The support unit elastically supports the optical device relative to the floating slider such that the optical device is movable in at least a substantially perpendicular direction relative to the recording surface of the medium. The optical device floats together with the floating slider over the medium. The floating slider has a through-hole formed in its center, and the support unit supports the optical device movably in the through-hole. The support unit includes an elastic element connecting the floating slider and the optical device. The optical head thus includes a separated slider and an optical device, wherein at least either the optical device or the slider is moved thereby performing at least tracking or focusing.
