A client station on computer network uses an operating system such as JavaOS which is permanently stored at the server rather than on storage media at the client location. JavaOS is loaded and installed at the client upon bootup of the client. Java is an interpreted language; the source is available at the server and is downloaded as such. Upon the occurrence of a malfunction that causes the client to go off-line, i.e., disappear from the network, a dump image is sent to the server before the client reboots, so that the cause of failure can be determined. The dump image includes the contents of memory, including the JavaOS operating system, and the stack, threads, registers, and local/global variables, which can be analyzed at a source level. This image is sent to the server in formatted packets, by a path separate from that of the TCP/IP network protocol, since the client would not be functioning properly on the network. At the server, the packets making up the dump image are stored on storage media, and the image is reformatted for use by a standard debugging tool, ICAT.

A memory system applied to an electronic device has a small-capacity linear-addressed nonvolatile memory having a boot code and system information stored therein and a high-capacity data flash memory in which an operating system (OS) and frequently accessed user data are recorded. While the memory system is booting up, the boot code including the system information is fetched from the linear-addressed nonvolatile memory to start an initialization process. After completion of the initialization process, the OS is retrieved from the data flash memory and executed. During the OS retrieval, the memory system provides an ECC/EDC unit to detect whether any bit error occurs and to correct any if present. Since the boot code and OS are stored in different memories, the bit error rate (BER) is effectively reduced.

A disc assembly in a disc drive includes a hub rotatable about a central axis. Pluralities of disc elements are mounted about outer periphery of the central axis of the hub. An annular shaped disc clamp is located about a first axial end of the hub, the annular shaped clamp holding the outermost disc to the hub by a series of equally spaced fasteners along an inner diameter of the disc clamp. The improvement therein consisting of placing an offset angle on the underside, or disc-to-hub contact area. The offset angle sloping from the inner disc contact point outward to the end of the clamp such that application of pressure during clamping will make a uniform contact area along the clamp surface as the clamp fasteners are tightened to secure the clamp to the hub. This improves flatness, axial run out, reduces repeatable run out and increases reliability.

Software atomization provides a method of loading atomized computer program code and data on demand by loading, from an atom database, into a memory, an atom defining code or data in a fine-grained, individually addressable manner. Atoms comprise an atom identifier, computer program code or data information and computer program code or data reference information. The computer program code or data information is modified by transforming the reference information into memory addresses. The present invention provides for the lazy loading of data both implicitly and explicitly. Data is lazily loaded implicitly when it is referenced from code that is lazily loaded. Data is lazily loaded explicitly by encoding a referencing atom identifier such that the referenced data atom is not loaded until actually accessed at runtime.
