Patent number: 7237249Abstract: A disk drive including a tray on which a disk cartridge is mounted and is loaded into and unloaded from a main body; a guide formed on the tray; and an opening and closing member installed to be elastically connected to the guide. The opening and closing member has a second gear that rotates a rotating wheel by meshing with a first gear; and a first protrusion formed on one end of a second gear and to temporarily rotate the rotating wheel so that the first and second gears can mesh. The guide pushes the first protrusion during loading/unloading of the tray so that the first protrusion and the latch do not come in contact with each other.Type: GrantFiled: January 31, 2005Date of Patent: June 26, 2007Assignee: Samsung Electronics Co., Ltd.Inventors: Jae-yong Eum, Yong-hoon Lee, Jeung-rak Lee, Hong-kyun Yim

Publication number: 20060026611Abstract: An optical disc drive having a vibration preventing device includes a main frame having sidewalls and a rear wall and guide rails inside the sidewalls; a disc tray with supporting steps to move to a disc loading/unloading position while supported by the guide rails to slide; and four elastic guides to absorb vibration of the disc tray by external impact and/or disc rotation by pressing and supporting the disc tray from up to down elastically, the elastic guides formed in the sidewalls to confront each other with a predetermined space. Since the elastic guides support the disc tray by pressing the disc tray in both sides of the back and front from up to down, the vibration of the disc tray may be prevented effectively. Although the disc tray is ejected to a disc unloading position, the disc tray is not shaken because the disc tray is still supported by two elastic guides.Type: ApplicationFiled: November 12, 2004Publication date: February 2, 2006Applicant: Samsung Electronics Co., Ltd.Inventors: Jeung-rak Lee, Young-bok Lee
