摘要： PURPOSE: A servo pattern erasing method of a hard disk drive and a device thereof are provided to uniformly erase a servo pattern recorded in a hard disc drive. CONSTITUTION: A servo pattern erasing method of a hard disk drive comprises the following steps. A servo pattern recorded in a disc is read(S1). An erase pattern for erasing a servo pattern is generated based on a servo pattern obtained from the reading step(S2). A servo pattern is erased by an erase pattern while rotating a disc(S3).

摘要： PURPOSE: A hard disk drive is provided to reduce the deviation of skew angle without increasing the size of the hard disk drive. CONSTITUTION: A hard disk drive comprises a disk(100), a magnetic head(200), and an actuator. The disk has a plurality of tracks in which information are recorded. The magnetic head records or reads information in a recording area of the disk. The actuator is equipped with the magnetic head and rotates to move the magnetic head from the outer track to the inner track of the disk. The ratio of the distance between the rotational center of the actuator and the magnetic head to the distance between the rotational center of the actuator and the center of the disk ranges from 0.96 to 0.9.
摘要翻译：目的：提供硬盘驱动器，以减少偏斜角度的偏差，而不会增加硬盘驱动器的大小。构成：硬盘驱动器包括盘（100），磁头（200）和致动器。盘具有记录信息的多个轨迹。磁头在磁盘的记录区域中记录或读取信息。致动器配备有磁头并旋转以将磁头从外轨道移动到盘的内轨道。致动器的旋转中心与磁头之间的距离与致动器的旋转中心与盘的中心之间的距离的比率为0.96至0.9。

摘要： PURPOSE: A hard disc drive is provided to prevent a disc centering from being deformed as the disc centering is enhanced by forming a centering maintaining unit on one or both of the inner and lower sides of a spacer body. CONSTITUTION: A hard disc drive(100) is composed of a motor hub(120), a plurality of discs(110), one or more spacers(130) and a clamp(140). Each spacer comprises a ring-shaped body and a first centering maintaining unit(134) formed on one or both of the inner upper side and the inner lower side of the spacer body. The cross section thickness of the first centering maintaining unit increases as it is close to the motor hub.
摘要翻译：目的：提供硬盘驱动器，以防止通过在间隔件主体的内侧和下侧的一个或两侧上形成定心保持单元来增强盘中心而使盘定心。构成：硬盘驱动器（100）由电动机毂（120），多个盘（110），一个或多个间隔件（130）和夹具（140）组成。每个间隔件包括环形主体和形成在间隔件主体的内侧上侧和内侧下侧之一或两者上的第一定心保持单元（134）。第一定心维持单元的横截面厚度随着靠近马达毂而增加。
