    • 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 patterns 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, eliminating 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,消除了对可重写数据层中预定轨迹的需要。 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。

    • The invention provides a chassis member, which may be made of a cast material such as magnesium, aluminum, or plastic, for mechanically supporting a heat producing electronic device in which the chassis member has a base and a cavity integral to the chassis member. In a preferred embodiment, the cavity is in the form of a channel that is created by boring. The channel may be evacuated and has an evaporator section, a condenser section, and a working fluid confined therein by a seal. The channel receives heat from an electronic device in an evaporator section of the channel and dissipates heat from the condenser section of the channel. Different types of wicks may be employed. In one embodiment, a completely fabricated heat pipe is inserted into the integrated channel. In other embodiments, a cavity in the form of a heat dissipating channel matrix, serpentine shape, flat shape, or in other forms or shapes are provided.

    • A self-testing and self-repairing memory system is presented as well as a method for using it and a method for making it. This memory system is constructed from memory chips that have passed an abbreviated wafer probe test. After the memory system is assembled, it tests itself to locate defective memory cells. The memory system may decide to correct these defective memory cells or it may decide to correct them using an error correction code engine. This memory system tests itself during field use to locate defective memory cells. Once these defective memory cells are located, the memory system uses the error correction code engine to correct these defective memory cells. When the error correction code engine becomes overburdened with defective memory cells, then the memory system replaces these defective memory cells.
    • 提出了一种自检和自我修复记忆体系统以及一种使用它的方法及其制作方法。 该存储器系统由已经通过缩写晶片探针测试的存储器芯片构成。 在内存系统组装完成后,它自行测试定位有缺陷的存储单元。 存储器系统可以决定纠正这些有缺陷的存储器单元,或者它可以使用纠错码引擎来决定修正它们。 该存储系统在现场使用期间测试自身以定位有缺陷的存储器单元。 一旦这些有缺陷的存储器单元被定位,存储器系统使用纠错码引擎来校正这些有缺陷的存储器单元。 当错误校正码引擎变得对存储器单元有缺陷时,存储器系统将替换这些有缺陷的存储器单元。
