An optical disk apparatus in which a head is accommodated in a movable part which moves the head along a guide shaft in a radial direction of an optical disk. The guide shaft is engageable with the movable part and extends in the radial direction of the optical disk. The optical disk apparatus has a guide shaft compression mechanism which applies a compression force toward the movable part, which force is distributed, approximately uniformly, along the radial direction of the optical disk, to the guide shaft so that the movable part can be properly engaged with the guide shaft so as to move smoothly and stably along the guide shaft in the radial direction of the optical disk.

A cleaning apparatus for an object lens which can provide a sufficient cleaning effect without affecting the supporting mechanism of an objective lens. The cleaning apparatus is inserted into a disk loading portion and cleans the object lens incorporated in an optical disk apparatus. The cleaning apparatus has a housing having approximately the same shape as the cartridge type optical disk. A brush protrudes from the housing and slide on the object lens when the cleaning apparatus in inserted into the optical disk apparatus. A sliding direction of the brush is set to be a predetermined direction between the inserting direction of the cleaning apparatus and a direction perpendicular to the inserting direction. Only components of force due to the sliding of the brush against the object lens, which components of force are smaller than the sliding force, are exerted to the object lens in a movable direction of the object lens for tracking adjustment and a direction perpendicular to the movable direction.

A disk storage device includes a head part which writes data into a storage disk loaded into the disk storage device and reads data from the storage disk, a linear actuator moving the head part in radial directions of the storage disk, an eject member which is operated when the storage disk is ejected, and a movement mechanism which moves the storage disk to an eject portion in response to an operation of the eject member and which moves the storage disk to a read/write position. A lock part, which has a lock member cooperating with the movement mechanism, keeps, in response to the operation of the eject member, the head part stationary at the eject position by the lock member which engages with one of the head part and the linear actuator.

A magneto-optical disk storage has an erroneous insertion preventing mechanism which projects into a holder so that it can touch the magneto-optical disk cartridge in order to prevent the same from being inserted. The erroneous insertion preventing mechanism mechanically engages with the magneto-optical disk cartridge and moves in a direction approximately vertical to the recording suface of the magneto-optical disk to allow the magneto-optical disk cartridge to be inserted only if the magneto-optical disk cartridge is being inserted into the holder with a correct orientation.
