Abstract
A lens support mechanism including a semiconductor laserfor emitting a laser beam, an optical head enclosureto which the semiconductor Laseris fixed and located, a collimator lensdisposed coaxially with the laser beam emitted from the semiconductor laser, a resin cylinderformed in a cylindrical shape so as to fix and locate the collimator lensto the inner surface thereof and a cylindrical memberfitted to the resin cylinderon a side of the collimator lensopposite to the semiconductor laserand formed so as to be fixed to the optical head enclosure. The cylindrical memberhas almost the same linear expansion coefficient as that of the optical head enclosure
