Abstract
An improved cooling device for cooling the magnetic head (M) of a magneto-optical disc player includes a plurality of arcuate ribs (R) formed as portions of concentric circles and having centers coincident with the axis of rotation of the disc player. The reading/recording head (M) is arranged between the ribs. The rotation of the disc in the proximity of the cooling device creates airflow between the ribs and serves to cool the magnetic head.
