    摘要: Provided is an optical recording medium driving apparatus including a light radiating unit that radiates light to an optical recording medium, a light receiving unit that receives reflection light from the optical recording medium, in which four regions including a first region, a second region, a third region, and a fourth region are formed by being divided by a linear direction division line and a tracking direction division line, a first binarizing unit that obtains binarization signals, a first exclusive OR calculating unit, a second exclusive OR calculating unit, and an operation unit. The first and second exclusive OR calculating units and the operation unit operate in a state not synchronized with a channel clock.
