Optical pick-up device and method of manufacturing the same

摘要

An optical pick-up device 1 comprises a laser diode 2 for recording which acts as a fixation side light source attached to an attachment portion 5 of a device frame 4 and has a great calorific value, and a laser diode 3 for reproduction which acts as an adjustment side light source held in a holder 6 fixed with an adhesive 7 in a clearance 46 provided on a side surface 45 of the device frame. Heat generated from the laser diode 2 for recording is radiated efficiently through the device frame 4, and heat generated from the laser diode 3 is also radiated efficiently through the holder 6 fixed with the adhesive 7 which is partially filled for the device frame 4 with the clearance 46 formed.
