Abstract: An image forming apparatus includes an apparatus body and a detachable unit to be attached to the apparatus body in an attachment direction and detached from the apparatus body in a detachment direction. The detachable unit includes a rotary body and a unit drive gear. The apparatus body includes an apparatus-body drive gear to engage with the unit drive gear of the detachable unit attached in the apparatus body, at an engageable position on a downstream side of the apparatus-body drive gear in the attachment direction. One or each of the unit drive gear and the apparatus-body drive gear moves to a retracted position at which the one or each of the unit drive gear and the apparatus-body drive gear does not engage with the other of the unit drive gear and the apparatus-body drive gear and does not interfere with attachment and detachment operations of the detachable unit.

Abstract: In a recording and reproducing apparatus, an optical disc is rotated in a rotating direction and an optical system focuses a laser beam on the optical disc to form a beam spot on the optical disc. The optical system is provided with a scanner which deflects the laser beam along a radial direction of the optical disc in such a manner that the beam spot follows a first scan trajectory along a first direction crossing the rotating direction and a second scan trajectory along a second direction different from the first direction. A first data track with a sequence of recording pits along the first scan trajectory is formed and arranged on the optical disc.
