摘要： A method for writing and reading data is performed on a dynamic memory circuit. The memory circuit has memory cells that can be addressed via word lines and bit lines. A word line is activated in the event of addressing of a memory area with a specific address. A word line has a plurality of mutually separate word line sections. Via the bit lines, in the event of addressing with the specific address, in parallel, a first number of data can be written to memory cells addressed by the address or the first number of data can be read from memory cells addressed by the address. In the event of addressing with a specific address, only a portion of the word line sections are activated, in order that only a portion of the memory cells connected to the word line are written to in parallel or read from in parallel.

摘要： A picking tool for an automated library of disk drive carriers has a body with a large guide pin, and a pair of electromagnets. The guide pin has an optical service interface at its tip. A disk drive is mounted to a carrier having a front bezel with a tapered hole that is complementary to the guide pin. The hole provides access to an optical service interface linked to the disk drive. The bezel also has a pair of embedded magnets located adjacent to its front surface. The carrier is located in and interconnected with a slot in an automated disk drive library. The guide pin is inserted into the hole so that the interfaces interconnect. The carrier is removed from the slot by activating the electromagnets on the picking tool to attract the magnets in the bezel. The tool picker then pulls the carrier out of the slot while supporting the weight of the carrier on the guide pin. The carrier is released from the picking tool by reversing the current through the electromagnets to repel the magnets in the carrier. The guide pin is then smoothly withdrawn from the hole by backing the picking tool away from the carrier.

摘要翻译： 用于磁盘驱动器载体的自动化库的拾取工具具有具有大引导件的主体和一对电磁体。 导针在其尖端处具有光学服务接口。 磁盘驱动器安装到具有带有与引导销互补的锥形孔的前挡板的托架上。 该孔提供访问链接到磁盘驱动器的光学服务接口。 挡板还具有一对位于其前表面附近的嵌入式磁体。 载体位于自动磁盘驱动器库中并与插槽互连。 引导销插入孔中，使接口互连。 通过启动拾取工具上的电磁铁将载体从槽中移除，以吸引挡板中的磁体。 然后，工具拾取器将支架从导槽上支撑出来，将支架拉出槽。 通过使通过电磁体的电流反转以排斥载体中的磁体，载体从拾取工具释放。 然后通过将拾取工具背离载体从导孔平滑地退出。

摘要： An apparatus separating a resonance excitation response of a first disc from a resonance excitation response of second disc, the apparatus includes spindle motor with a spindle motor hub supporting the first disc, a disc spacer communicating with the first disc supporting a second disc and a clamp ring attached to this on the motor hub imparting a clamping force on the second disc to form a disc pack. Separation of resonance response between the first disc and the second disc results from maintaining a distinction between an amount of extension of mass and stiffness of each disc available for resonance excitation beyond respective outboard clamping points of the disc spacer. Separation of resonance assures resonance of the first disc is dissipated by a damping of the spindle motor, as well as resonance of the second disc is dissipated by the damping of the spindle motor.
