16 ABSTRACT ACCESSING AND TRACKING DEVICE FOR OPTICAL DISKS The present invention concerns a device for accessing and following tracks on the surface of mobile media containing data optically readable and/or writable by a laser beam, the said device including at least one optical head made up of a rigid carriage which enables the laser beam to access the reading and/or writing track, of a lens rigidly linked to the rigid carriage and intended to focus the laser beam on the surface of the mobile data medium, of a return mirror linked rigidly to the rigid carriage and intended to direct the laser beam towards the lens, of at least one motor coil which allows movements of the carriage intended to focus the laser beam, and a mirror not fixed to the optical head and which allows the laser beam to be directed towards the optical head as well as a motor coil allowing said mirror to pivot, wherein it includes means for detecting and correcting any decentering of the beam in relation to the axis perpendicular to the plane of the pupil of the lens and passing through its center, the correction being applied along the direction defined by the axis perpendicular to the said axis and contained in the plane perpendicular to the plane of the pupil and containing the center of the return mirror and the center of the mirror which allows the laser beam to be directed towards the optical head. The present invention is applicable to reader/recorders of mobile media containing optically readable or recordable data. Figure 2
