Abstract: One embodiment of a camera module includes: a lens barrel provided with at least one lens; and a lens holder having the lens barrel coupled thereto, wherein the lens barrel may have a first adhesive part formed thereon having the bottom surface thereof facing the top surface of the lens holder and adhered to the lens holder, the lens holder may have a second adhesive part formed thereon having the top surface thereof facing the bottom surface of the lens barrel and adhered to the lens barrel, and a first recessed groove having at least a portion of an adhesive deposited therein may be formed in the second adhesive part.

Abstract: A method and apparatus for controlling an audio recording level. The apparatus variably controls a recording level of audio data recorded on a rewritable recording medium such as a DVD-RW disk on the basis of either a firstly-recorded audio level average value in song units or a previously-recorded audio level average value in song units, and then records the resultant data on the recording medium. In this way, the apparatus records the audio data to be recorded on a single recording medium at a prescribed audio recoding level within the appropriate range, resulting in even playback audio levels regardless of the type and/or format of audio data.
