Abstract
A disc drive apparatus comprises a housing; a disc-holding unit that holds an optical disc in the housing; a disc-driving mechanism that rotates the optical disc held by the disc-holding unit; an optical pickup that writes signals in, and reads signals from, the optical disc being rotated by the disc-driving mechanism; and a pickup-moving mechanism that moves the optical pickup in a radial direction of the optical disc. The housing has an air-inlet port which is located above the optical disc held by the disc-holding unit and through which air is drawn from outside by virtue of an airflow that develops as the optical disc is rotated, and air-outlet ports through which air is discharged from the housing.
