摘要： A recording disk drive includes a restriction member located within an enclosure at a location opposed to a slant. The slant is defined on a ramp member so as to get closer to a recording disk at a location closer to the center of the recording disk. The slant is designed to receive the tip end of a head actuator supporting a head slider. If an impact acts on the recording disk drive during the movement of the head slider toward the recording disk or off the recording disk, the tip end of the head actuator tends to jump up from the slant. Here, the tip end of the head actuator is received on the restriction member. The restriction member thus serves to reliably prevent the head slider from jumping up. The head slider is prevented from colliding against the enclosure.

摘要： This recording medium drive has an actuator member which rotationally moves around a first shaft, a latch stop member fixed to the housing, and a latch member which rotationally moves around a second shaft. The actuator member, having a locked member, and the latch member has a locking member which restrains the rotational movement of the actuator member and a coefficient of repulsion between the latch stop member and the latch member is a coefficient of repulsion such that, in the event that the housing receives an impact when the actuator is in a standby state, the locking member of the latch member reaches a lockable rotation angle before the locked member of the actuator member reaches the lockable rotation angle. In the event that various impacts are applied, it is possible to prevent the actuator member from jumping out to the recording medium.

摘要： A lever and a weight are supported on a first shaft for swinging movement in a latch mechanism. The weight gets closer to a head actuator member based on swinging movement in a first direction. A restriction member restricts the swinging movement of the weight in a second direction opposite to the first direction. A swinging member is contacted with the lever swinging around the first shaft so that the swinging member gets into a predetermined path of the head actuator member through the swinging movement around the second shaft. The disk drive always allows the weight, the lever and the swinging member to start swinging from corresponding inoperative positions, even if the disk drive suffers from a sequential driving force in opposite directions due to impact. A head slider at the tip end of the head actuator member is reliably prevented from colliding against the disk.

摘要： A recording medium drive such as a hard disk drive includes a ramp member. The ramp member receives the tip end of a head actuator. A head slider is thus kept at a position spaced from the recording medium even when the recording medium stands still. A rectifier plate is formed on the ramp member and opposed to the surface of the recording medium at a distance. The rectifier plate serves to sufficiently suppress turbulence of airflow generated along the surface of the rotating recording medium. The suppression of the turbulence in this manner leads to prevention of oscillation of the head slider. The head slider can thus be positioned right at a target point at a higher accuracy. The recording medium drive of the type is capable of greatly contributing to a higher recording density.
摘要翻译：诸如硬盘驱动器的记录介质驱动器包括斜坡构件。斜坡构件接收头致动器的末端。因此，即使当记录介质静止时，磁头滑块也保持在与记录介质隔开的位置。整流板形成在斜坡构件上并与记录介质的表面相隔一定距离。整流板用于充分抑制沿旋转记录介质表面产生的气流的湍流。以这种方式抑制湍流导致防止磁头滑块的振荡。因此，头部滑动器可以以更高的精度定位在目标点处。该类型的记录介质驱动能够极大地有助于提高记录密度。

摘要： A recording medium drive allows a latch stop member to receive a latch member. The swinging movement around a rotation shaft causes the latch member to enter the movement path of a head actuator member. The latch member thus engages with the head actuator member. The latch member has the portion in contact with the latch stop member. The portion is made of a material different from the main portion of the latch member. The repulsive coefficient can be adjusted between the portion and the latch stop member. An identical condition can be established for transmission of an impact between the head actuator member and the actuator stop member as well as between the latch member and the latch stop member. Even if impacts of different duration act on the recording medium drive, the latch member is allowed to reliably engage with the head actuator member.
摘要翻译：记录介质驱动器允许闩锁止动构件接收闩锁构件。围绕旋转轴的摆动使闩锁构件进入头致动器构件的运动路径。因此，闩锁构件与头致动器构件接合。闩锁构件具有与闩锁止动构件接触的部分。该部分由与闩锁构件的主要部分不同的材料制成。可以在部分和闩锁止动构件之间调节排斥系数。可以确定在头致动器构件和致动器止动构件之间以及在闩锁构件和闩锁止动构件之间的冲击传递的相同条件。即使不同持续时间的冲击作用在记录介质驱动器上，允许闩锁构件可靠地与头致动器构件接合。

摘要： A head actuator member is supported on a support shaft for swinging movement. A voice coil motor is connected to the head actuator member. A protuberance is formed on the head actuator member. The protuberance moves along a predetermined movement path around the support shaft. A latch member is supported on a rotation shaft for swinging movement to reach an operative position established on the movement path of the protuberance. The latch member engages with the protuberance at the operative position. A magnetic body on the latch member receives a magnetic attraction of the voice coil motor when the latch member is located at the operative position. The latch member is forced to stay at the operative position. Even if the head actuator member starts swinging later than the swinging movement of the latch member, the latch member reliably engages with the protuberance on the head actuator member.
