摘要： A disk drive unit for a disk includes a mounting plate, a spindle motor assembly, a slide mechanism provided with a slide, a pickup unit mounted on the slide, a first transmission member operatively connected with the slide, and a second transmission member. The first transmission member is positioned such that it is in engagement with the second transmission member when the pickup unit is in its read and/or write position, and such that the first transmission member is out of engagement with the second transmission member when the pickup unit is in its home position. In order to bring the first and second transmission members into engagement, the transmission members are provided with engagement members. As a result, a limit switch assembly is no longer necessary.

摘要： An apparatus which provides improved positional control for an access element moveable adjacent a rotatable surface, such as a data transducing head adjacent a data recording disc in a data storage device. The apparatus comprises a fluidic stripper with one or more cantilevered arms which project proximate a corresponding array of one or more rotatable surfaces. Each arm comprises an edge surface which extends proximate to and in facing relationship with a movement path of an access element across the associated rotatable surface to impede fluidic currents established by rotation of the rotatable surface. Each arm further supports a ramp structure which receivingly supports the access element at a position away from the rotatable surface and proximate the innermost diameter during a deactivated mode when the rotatable surface is stationary.

摘要： To supply a pivot assembly for hard disk drive use that can reliably fix a seal member and solve the problem of out gas, thus reducing the expense and time incidental to the pre-load of a ball bearing. Ball bearings have been joined to both ends of a shaft, and on the outer circumference of these ball bearings, the spacer part is joined to a sleeve disposed between both ball bearings, and a seal member that covers the outer end of the ball bearing has been fixed to the outer circumference of the shaft by laser welding. Because the seal member is fixed by laser welding, the seal member can be reliably fixed and the problem of out gas from the seal member can be solved.

摘要： A method and system of switching heads in a hard disk drive written using an off-line STW method. In the method, first, deviations between a reference head and each of the heads are calculated. Next, a mapping table having the deviations between the reference head and each of the heads is generated and stored in a memory. Thereafter, when a head switching operation is requested, a current head is switched to a new head to access a track whose number is the same as the track assessed by the current head. A deviation of a track on which the head is positioned, recorded in the mapping table, is applied to the virtual track address of the track on which the head is positioned, thereby obtaining the physical track address of the track on which the head is positioned. The requested track is then accessed based on the obtained physical track address. As described above, in the head switching method, even when disks for a hard disk drive are written using an off-line STW method, the individual disks can be accessed based on an identical virtual track address. Thus, the performance of the hard disk drive is not degraded.
摘要翻译：在使用离线STW方法写入的硬盘驱动器中切换磁头的方法和系统。在该方法中，首先计算参考头与每个头之间的偏差。接下来，生成具有参考头和每个头之间的偏差的映射表并将其存储在存储器中。此后，当请求头切换操作时，将当前头切换到新头以访问其数量与由当前头评估的轨迹相同的轨道。记录在映射表中的磁头位于其上的磁道的偏差被施加到磁头所在磁道的虚拟磁道地址上，由此获得磁头所位于的磁道的物理磁道地址。然后根据获得的物理轨道地址访问所请求的轨道。如上所述，在磁头切换方法中，即使使用离线STW方法写入用于硬盘驱动器的磁盘，也可以基于相同的虚拟磁道地址来访问各个磁盘。因此，硬盘驱动器的性能不会降低。

摘要： A disk unit has a function of loading a head on a disk from a holding mechanism during a load operation and unloading the head from the disk during an unload operation. The disk unit includes a controller which controls a movement of the head so that the loading operation and the unloading operation are carried out in a specific region on the disk, and the specific region extends for an angular range smaller than 360°. Alternatively, the controller controls the movement of the head so that the loading operation and the unloading operation are carried out uniformly in a circumferential direction of the disk within a specific region on the disk.
