Abstract
A magneto-optical disc recording apparatus with a high mounting efficiency and shortened access time, wherein two magneto-optical disc media are disposed facing each other, only the outside of the two magneto-optical disc media being recordable and reproducible, auxiliary magnetic field application magnets are disposed between the two magneto-optical disc media, and the reproduction/recording heads and reproduction/erasure heads are affixed on the same bases which are mounted on a sled base, whereby it becomes possible to reduce the size of the plane of the sled base, dispose a large number of heads, and shorten the access time as well.
