1. A disk drive comprising:
a main chassis; a tray operatively coupled to the main chassis such that the tray is slidable relative to the main chassis, the tray comprising a disk accommodation portion configured to accommodate a storage medium such that the storage medium is rotatable relative to the disk accommodation portion; and a noise reduction unit configured to reduce a pressure concentration on an end portion of the storage medium in response to the storage medium rotating to reduce noise, wherein
the noise reduction unit is formed on a rear side of the tray that is configured to be furthest inserted into the disk drive, and in a semicircular pattern spaced from an outer edge portion of the disk accommodation portion and corresponding to a location of an outermost circular edge of the storage medium, andthe noise reduction unit comprises air flow holes disposed along an interior of a disk scratch prevention portion formed along an outer circumference portion of the disk accommodation portion, the air flow holes extending past boundaries of a continuous section of the disk scratch prevention portion on both sides of the continuous section.
