Design and analysis of anti-vibration system for the stylish dvd deck

Abstract

Up to recently, the ODD(Optical Disk Drive) decks for CD and DVD have been mostly manufactured to be operated horizontally. Anti-vibration problems for this type of ODD deck have been concentrated on making focusing and tracking servo safe, when the deck is laid horizontally and is affected by disturbance, shock, vertical deviation or planner vibration of the disk, eccentricity, or radial run-out of the disk, tilt, etc. But consumers‘ various tastes have led to a demand for the deck like the stylish DVD player that can be laid in any directions, such as horizontal, vertical, upward, hanging on the wall and even being arbitrary position like a picture frame. Therefore, it is essential that we observe carefully this kind of deck mechanism and cope with the vibration problems of the deck in various positions. The purpose of this paper is to design the slot-in type deck mechanism that can be placed in all directions, to design and analyze the anti-vibration system for this type of deck, and to prove its propriety through transmissibility experiments and external vibration tests.
