Problems solved by technology

[0007] However, the above-mentioned calibration operation is performed inside the disk, so the clamping state must be continuously maintained during the data recording process, which will cause the disk to deform
In addition, since the flat chuck performs clamping and centering operations at the same time, the internal structure becomes complicated, making it difficult to maintain the disk centering device
In addition, due to the increased weight of the flat chuck, the centrifugal force generated during rotation increases, thereby creating vibration problems due to the rotation of the disc

Abstract

A disc centering device includes a base plate, a chuck which is installed on the base plate, a hub unit which is detachably engaged to the chuck and receives discs to be stacked, disc pushers which are slidably provided outside the hub unit and include corresponding pressure members which center the discs by pushing circumferences of the discs, and a driving unit which slides the disc pushers simultaneously. Accordingly, as the accuracy of centering the discs is improved, discs with data recorded thereon having a uniform quality can be obtained. Additionally, vibration of a rotation body can be minimized due to the simple configuration the disc centering device. Therefore, in view of the simplified maintenance and repair of the disc centering device, the productivity and manufacturability of HDDs can be improved.

Description

technical field [0001] The present invention relates to a disk centering device for centering a large number of disks. Background technique [0002] Generally, HDD (Hard Disk Drive) is a type of secondary storage that records and retrieves data using its magnetized aluminum platter. In the case of using one or more high-density and high-capacity HDDs, it is difficult to record data after assembling one or two HDDs. In order to solve this problem, a method of assembling HDDs and recording data thereon after mounting a plurality of HDDs on a chuck has been introduced. [0003] In this method, in order to prevent vibration due to recording data, it is necessary to use a centering device to perform a centering operation so that a plurality of disks have the same disk center. [0004] According to a conventional disk centering device, a plurality of disks are centered by pushing the circumference of the disks using a pushing unit. Korean Patent Application No. 1996-53058 filed...
