ABSTRACT:
A support frame for an optical disk unit where reduction in thickness and/or weight saving can be realized and the optical disk unit are intended to be obtained.In an optical disk drive unit, a support frame2has neither upper cover nor bottom cover, and is formed from a frame that continuously encloses both sides and a back of a disk tray1without any cutout portions in order to secure strength, and furthermore, the support frame2is manufactured by a die casting method using a metal material such as aluminum material, zinc material, and magnesium material, or by a press method using a metal sheet such as iron sheet, aluminum sheet, and magnesium sheet, or by composite molding using a polymer such as PPS (polyphenylenesulfide), POM (polyacetal), and LCP (liquid crystal polymer) with the metal sheet, or by a forging method using a metal material such as aluminum, thereby strength that prevents the optical disk drive unit as a whole from distorting or deforming during operation or actuation is secured.
