Problems solved by technology

[0013] However, most of the above-mentioned conventional centering methods reduce the unbalance amount not by accurately performing the centering of the disk, but by using an additional process of measuring the unbalance amount after assembly, or by only allowing The basic imbalance of the disk reaches a certain level
Therefore, the quality characteristics of each disc vary, thereby seriously affecting recording characteristics or mass production characteristics
[0014] Specifically, even if the centering process is performed by the above-mentioned centering method using an expensive centering device or an unbalanced device, a slip phenomenon occurs during the rotation of the disk, and thus the set value is changed from the initial value changes
Therefore, it will affect the quality characteristics during the use of STW or HDD, for example, RRO or NRRO

Abstract

The invention provides a disk spacer for data storage device and a hard disk drive having the same. The hard disk drive includes a hub on which a plurality of disks are rotatably assembled, and a spacer assembled to the hub to be alternately arranged with the disks to separate the disks and having at least one area of an inner wall surface that elastically contacts and is pressed against an outer wall surface of the hub for centering with respect to the hub.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2010-0004586 filed with the Korean Intellectual Property Office on Jan. 19, 2010, the entire disclosure of which is hereby incorporated by reference. technical field [0002] The present inventive concept relates to a disk separator of a data storage device and a hard disk drive (HDD) having the same, and more particularly, to a disk separator of such a data storage device and an HDD having the same , the disk separator has a simple structure and can be automatically centered with respect to the hub, so that the disks can be easily centered without expensive equipment, the mass characteristics of each disk can be kept constant, and it is possible to prevent repeatable Effects of off-orbit (RRO) or non-repeatable off-orbit (NRRO). Background technique [0003] When performing servo track writing on a disc using a servo track writing (STW) apparatus or manufacturing an HDD, a plurality of discs are ...
