Embodiment Construction

[0039] Preferred embodiments of the present invention will be described below with reference to examples shown in the accompanying drawings.

[0040] A number of embodiments of anti-vibration means for disk drives can be envisaged, and those of the more preferred embodiments of the invention are described below.

[0041] image 3 is a perspective view of a disk drive in which the shock absorber of the present invention is used.

[0042] refer to image 3 , the disk drive includes a housing 11, a tray socket 12 is formed on the front surface of the housing, and a connector (not shown) is provided so that the drive can be connected to the printed circuit board inside the notebook computer, thereby receiving and sending signals to the notebook computer .

[0043] The tray unit 13 is mounted to be movable between a position in which it is fully inserted into the housing 11 and a removal position as shown, in which the tray unit 13 protrudes from the housing 11 for loading or Rem...

Abstract

An antivibration device for a disk drive which is equipped in a notebook computer, desktop computer, CD playing device or DVD playing device to reproduce CD and DVD disk and which includes a pick-up unit in which a pick-up is mounted to reproduce information recorded in a disk or record information in the disk. A pick-up unit supporting unit has an upper supporting member and a lower supporting member positioned above and below the pick-up unit and the upper supporting unit and lower supporting unit are fixed mutually in a separated position having a certain interval therebetween through a fixing member. A vibration damper supports the pick-up unit between the upper supporting member and the lower supporting member of the pick-up unit supporting unit. The vibration damper has the pick-up unit fixed on its outer circumferential surface and a plurality of contact protrusions are formed on at least one surface among the upper surface and the lower surface attached to the pick-up unit supporting unit.

Description

technical field [0001] The present invention relates to a disk drive equipped in a notebook computer, a desktop computer, a CD player, or a DVD player capable of reproducing CD disks and DVD disks, and more particularly, to a disk drive for such a Anti-vibration devices that dampen vibration and noise in the various components of the disk drive. Background technique [0002] Recently, the speed of optical disc drives such as CD-ROM drives and DVD-ROMs has been increased to 16X, 24X, and 48X, and due to the increase in the speed of optical disc drives, severe vibration problems occur when driving optical discs. [0003] In particular, when a disc whose center of gravity is tilted is driven at high speed, the force of internal vibrations generated during the rotation period of the disc increases in proportion to the rotation speed of the disc, and when installed in portable information processing equipment and the like In a disc drive, the above-mentioned internal vibrations ...
