ABSTRACT:
An information recording apparatus has first and second openings arranged near a field coil and flow guides beside the openings, so that an air current generated by a rotation of the medium is circulated through a space between a field coil and the information recording medium, as well as a space formed on an upper portion of said field coil. In the apparatus, an optical pick up is locked with respect to reckless stoppers with a space. Also, a field holder is arranged to be separated from a cassette case holder, but when the cassette case holder is moved in a horizontal direction and then in a perpendicular direction to be mounted on a turn table, the field holder is made to face the information recording medium. This arrangement prevents overheating and improves durability.
