According to one embodiment, a disk apparatus has a disk, a head, a carriage assembly, and a circulation filter provided at the corner of the base, located downstream of the head with respect to a rotating direction of the disk. A sidewall of the base has a confronting surface which continuously extends along the outer peripheral edge of the disk, is formed in an arc, and confronts with the outer peripheral edge of the disk with a gap. The base has a guide flow path 58 which is formed in the sidewall in a corner and guides an airflow to the circulation filter. The guide flow path has an inlet port and an outlet port which open to the confronting surface of the sidewall in the corner at positions away from the positions at which they confront with the outer peripheral edge of the disk.
