A refrigerator includes a handgrip arranged on one side of a door to open and close a storage compartments, a measurer configured to measure fingerprints and body composition of a user when the user grabs the handgrip, a display configured to display the measured body composition information, and a controller configured to recognize the user based on the measured fingerprints and store the measured body composition information as information regarding the recognized user.

Refrigerator and method for measuring body composition using the refrigerator

A method of, and an apparatus for detecting a radial tilt of a disc. Phases of summed signals obtained from signals that external light-receiving units of an octant photo diode receive are compared to generate an external phase comparison signal Do. Phases of other summed signals obtained from other signals, that internal light-receiving units of the octant photo diode receive, are compared to generate the internal phase comparison signal Di. The radial tilt is detected based on the internal and external phase comparison signals Di and Do obtained when a laser beam crosses a track formed the disc. Thus, the radial tilt can be more precisely detected.

Method and apparatus for detecting radial tilt

A recording and/or reproducing apparatus and a method of controlling the same. The method of controlling the apparatus for recording information in or reproducing information from a disc having a wobbled track, the method includes detecting a wobble signal recorded in the wobbled track, and removing an error component occurring during the recording or the reproducing, based on the detected wobble signal. Accordingly, errors arising from a variety of factors can be accurately compensated for during a recording or reproducing operation.

Recording and/or reproducing apparatus and method of controlling the same

An apparatus for and a method of producing a push-pull tracking error signal in an optical disc system having four light-receiving sections A, B, C, and D arranged in a radial direction of the optical disc. Pairs of signals P, P, Pand P, corresponding to light receiving sections A, B, C and D, respectively are differentially combined to provide differential signals. One differential signal is filtered, amplified and differentially combined with another differential signal to output a tracking error signal. Accordingly, distortion of the tracking error signal during jumping to a desired track and distortion of the tracking error signal due to a defect of the optical disc are prevented.
