    • A disk clamp has a data position in a recording track that is resistant to positional deviations even after temperature cycling is conducted. The distribution of data positions can be centered in the vicinity of the center position. A disk top clamp and hub are made from materials that are stable in terms of chemical properties over a temperature range in which the disk recording apparatus is used and have such a coefficient of elasticity that a clamping force required to clamp the recording disks while the disk recording apparatus is in use can be obtained from the tightening force to tighten the screws. The material of the top clamp and the hub has a thermal expansion coefficient that is close to that of the recording disk.
    • 即使在进行温度循环之后,盘式夹具也具有能够抵抗位置偏差的记录轨迹中的数据位置。 数据位置的分布可以在中心位置附近居中。 盘顶夹具和轮毂由在使用盘记录装置的温度范围内在化学性质方面是稳定的材料制成,并且具有这样的弹性系数,使得在盘片上夹紧记录盘所需的夹紧力 记录装置正在使用中可以从紧固力获得拧紧螺丝。 顶部夹具和轮毂的材料具有接近记录盘的热膨胀系数。

    • The present invention provides an integrally formed ramp that is used for evacuating the suspension arm of a data storage device. The ramp has sliding portions, each having guiding zones and a landing zone. The boundary between the guiding zones and the landing zone is formed parallel to a reference line, so even if the landing portion had a recessed shape, the sliding portion could be molded with a casting mold by pulling out the casting mold in the direction of the reference line. The necessary portion of a support portion which is formed with the same casting mold as the sliding portions is formed so as not to disturb the pulling-out of the casting mold in the direction of the reference line. The integrally molded ramp is high in fabrication accuracy and excellent in defining an accurate loading/unloading position of the suspension arm.
    • 本发明提供一种整体形成的斜坡,用于对数据存储装置的悬架臂进行抽空。 坡道具有滑动部分,每个滑动部分具有引导区域和着陆区域。 引导区域和着陆区域之间的边界与参考线平行地形成,因此即使着陆部分具有凹形形状,也可以通过沿铸造模具的方向拉出铸模来模制滑动部分 参考线。 形成有与滑动部相同的铸模的支撑部的必要部分被形成为不会妨碍铸模在基准线的方向上的拉出。 整体模制的斜坡的制造精度高,并且在限定悬架臂的精确加载/卸载位置方面优异。

    • A ramp wherein the amount of deformation in the front end edges of guiding parts caused by thermal expansion. The ramp includes at least two guiding parts individually formed for each suspension arm and made of a polymeric material having a small friction coefficient for guiding the suspension arm by sliding into a accommodation zone, and a guide supporting member made of a material having a thermal expansion coefficient smaller than that of the polymeric material of the guiding part for supporting each guiding part at a predetermined position. The guide supporting member has guide support holes which are located in zones to be contacted with the associated guiding parts, are not contacted with associated recording disks, and are engaged with the associated guiding parts at such positions that distances to the front end edges of the guiding parts become shortest. Each of the guiding parts has a projection. When the projection is engaged in the associated guide support hole, the guiding part guides the suspension arm at a suitable position.

    • A ramp 200 has an attaching portion 221 and an arm holding portion 222. The attaching portion is molded with high polymer material so that the attaching portion has a screw hole 25 for fixing the ramp to the housing of an information recording disk apparatus by a screw. The arm holding portion is molded with high polymer material whose fiction coefficient is small, and the arm holding portion has a storing portion 27 to hold the suspension arm retracted from the recording disk and also has a guide portion 28 against which the suspension arm slides so that it is easily moved in and out of the storing portion 27. The attaching portion 221 and the arm holding portion 222 are united in one by subsequently molding the attaching portion and the arm holding portion.
