Abstract

A disk apparatus to which a cartridge accommodating a disk for recording or reproducing information thereon is loaded, the cartridge having a shutter capable of opening so as to expose the disk is provided. The disk apparatus includes: a disk transporting section for transporting the cartridge from an unloaded position to a loaded position; and an opener for opening the shutter in a slide direction which is perpendicular to a transportation direction of the cartridge. A leading end face of the cartridge in the transportation direction of the cartridge has a first end face and a second end face, the first end face extending in the transportation direction and the second end face extending in the slide direction. The shutter is opened responsive to a pressurizing force applied in the slide direction to the first end face from the opener. The opener applies a pressure to the first end face, but does not substantially apply a pressure to the second end face, during substantially a first half of an opening operation of the shutter.
