    • An optical disk and compatible optical disk drive enabling erasable (rewritable) optical disks to have the same format and capacity as read-only or (recordable) write-once optical disks. A reference clock track and optional additional prerecorded phase synchronization patters are provided to enable writing of any random sector with frequency and phase matching of a random sector to the preceding and following sectors. The reference clock track and other phase synchronization patterns eliminate the need for preambles and extra space for speed variation. In a first embodiment, a disk has multiple layers, with at least one rewritable data layer and at least one reference layer. A spiral track on a surface of the reference layer has prerecorded patterns to be used for clocking. In a variation of first embodiment, the reference layer is also used for radial tracking control, eliminated the need for predefined tracks in the rewritable data layers. The reference layer is produced using the same technology as for read-only media, and is therefore very precise, low cost, and permanent. An additional laser system may be required to read the reference layer. The rewritable data layers may be unpatterned prior to writing. Alternatively, the rewritable data layers may include embossed sector or block headers to augment clock phase precision. In a second example embodiment, a single circular permanent (non-erasable) clock track is provided on a rewritable medium. The disk is then divided into radial zones, so that within each zone, the angular velocity of the disk is constant. A clock signal from the permanent clock track is then ratioed for each radial zone.
    • 光盘和兼容的光盘驱动器,使可擦除(可重写)光盘具有与只读或(可记录)一次写入光盘相同的格式和容量。 提供了参考时钟轨道和可选的附加预记录相位同步模式,以便能够将随机扇区的频率和相位匹配的任何随机扇区写入前一个和后续扇区。 参考时钟轨道和其他相位同步模式消除了前导码的需要和速度变化的额外空间。 在第一实施例中,盘具有多个层,具有至少一个可重写数据层和至少一个参考层。 参考层表面上的螺旋轨迹具有用于计时的预先记录的图案。 在第一实施例的变型中,参考层也用于径向跟踪控制,消除了在可重写数据层中对预定轨迹的需要。 参考层使用与只读介质相同的技术生产,因此非常精确,低成本和永久性。 可能需要额外的激光系统来读取参考层。 可写入数据层可能在写入之前未被图案化。 或者,可重写数据层可以包括压花扇区或块标题,以增加时钟相位精度。 在第二示例实施例中,在可重写介质上提供单个永久(不可擦除)永久(不可擦除)时钟轨道。 然后将磁盘分成径向区域,使得在每个区域内,磁盘的角速度是恒定的。 然后,对于每个径向区域,来自永久时钟轨道的时钟信号成比例。

    • A defect management enabled PIRM including a data storage medium providing a plurality of cross point data storage arrays. Each array provides a plurality of memory cells. The arrays are allocated into separate super arrays, the separate super arrays virtually aligned as sets. A controller is also provided, capable of establishing the selection of a virtually aligned set of arrays and a virtually aligned set of memory cells. The controller is operable during a write operation to receive a word of data bits and detect a defective array in the selected virtually aligned set of memory arrays. The controller is further capable of directing the allocation of at least one data bit from the defective memory array to a spare memory array.

    • An electrostatic actuator having two-dimensional in-plane motion of a monolithic element suspended by flexures which is unstable in the open-loop and uses feedback control to operate. By adding a common bias voltage to each of the stator electrodes when the translator and stator are in the unstable equilibrium position, repulsion can be reduced to zero while the in-plane force remains in unstable equilibrium. Stabilizing the in-plane force at the unstable equilibrium position is achieved by shifting the electrical phase of the stator potential distribution in a direction to produce an in-plane force which opposes motion of the translators away from the equilibrium position. Linear control and pulse width modulation control permit altering the phase by less than the stator pitch. The drive electrodes of the translator and stator are used as position sensors for in-plane and out-of-plane relative displacements of the translator and stator concurrent with operation of the motor using either pulse-width modulation or linear control.
    • 具有通过在开环中不稳定并且使用反馈控制进行操作的挠曲而悬挂的整体元件的二维平面内运动的静电致动器。 当平移器和定子处于不稳定的平衡位置时,通过向每个定子电极添加一个公共的偏置电压,排斥力可以减小到零,同时平面内的力保持不稳定的平衡。 通过在一个方向上移动定子电势分布的电相以产生与平移位置的平移位移相反的平面内的力来实现在不稳定平衡位置稳定平面内的力。 线性控制和脉宽调制控制允许相位小于定子间距。 转换器和定子的驱动电极用作位移传感器,用于使用脉宽调制或线性控制与电机的运行同时进行平面和平面外平面相对位移。
