Abstract

Optical disc drive comprising an optical pickup head slidably supported by guide bars (4, 4'), a driving shaft (7) and a follower (3) for transmitting rotation of said driving shaft into a displacement of said optical pickup head. The follower comprises a tooth holder (10) engaging a groove (11) of the driving shaft during normal use. The follower further comprises a stopper (13) which at least abuts the side of the driving shaft that is faced away from the tooth holder. The stopper is configured to restrict said driving shaft to move away from the tooth holder utilizing spring force.
