摘要： A single chip integrated disc/servo controller and processor (CPU) for a disc drive reduces timing overhead associated with processor/controller/memory communication paths, increases speed, reduces the number of ASIC components, and increases reliability. The processor has a core that can be customized and implemented with appropriate hard disc drive specific controller technology including code or algorithms. Timing overhead associated with the conventional multi-chip communication paths is reduced by the inventive structure as the single on-chip processor has direct access to a buffer memory through a buffer manager within the controller logic. This eliminates the pin and pad delays that are present in conventional implementations. This performance increase has a direct positive impact on disc drive performance generally, and more particularly on disc drive performance when running code from the buffer memory. The structure and method also reduce overhead when communicating with the controller logic, and reduces the delays and other timing overhead associated with accesses to individual storage registers, which are generally slower in the conventional multi-chip configuration than in the single-chip integrated device. Single-chip integration also advantageously reduces product cost by removing one of the ASICs that would otherwise be required for the disc drive electronics. The single chip integration provided by the invention also advantageously includes structural features implemented in sub-micron semiconductor manufacturing technology to provide the aforementioned integration.
摘要翻译：用于磁盘驱动器的单芯片集成光盘/伺服控制器和处理器（CPU）可减少与处理器/控制器/存储器通信路径相关的定时开销，提高速度，减少ASIC组件的数量，并提高可靠性。处理器具有可以通过适当的硬盘驱动器特定控制器技术（包括代码或算法）来定制和实现的核心。与传统的多芯片通信路径相关联的定时开销由于本发明的结构而减少，因为单个片上处理器通过控制器逻辑内的缓冲器管理器直接访问缓冲存储器。这消除了传统实现中存在的引脚和焊盘延迟。这种性能提高对于一般的磁盘驱动器性能具有直接的积极影响，特别是当从缓冲存储器运行代码时的磁盘驱动器性能。结构和方法还减少了与控制器逻辑通信时的开销，并且减少了与单个存储寄存器的访问相关联的延迟和其他定时开销，这在常规多芯片配置中比在单芯片集成器件中通常较慢。单芯片集成还有利地通过去除另外一种对于盘驱动电子装置所需的ASIC来降低产品成本。本发明提供的单芯片集成还有利地包括以亚微米半导体制造技术实现的结构特征，以提供上述集成。

摘要： A data sector/servo split generator is disclosed for a disk drive apparatus implementing a zone bit recording format and having an embedded sector servo system where servo sector fields split at least one data field on a surface of a disk in the disk drive apparatus. A first counter is provided to count an amount of time to the beginning of a data field, and a first signal (SECTOR) is generated to indicate when the beginning of a data field is encountered by a read/write head in the disk drive. A second signal (SPLIT.sub.-- VALID) is generated by the data sector/servo split generator if a next data field after the generation of the SECTOR signal is split by a servo sector field. A second counter counts a predetermined number of data bytes transferred between a surface of a disk in said disk drive apparatus and said disk controller, so that a third signal (SPLIT) is generated, the SPLIT.sub.-- VALID signal is generated, when a servo sector is encountered in a data field by the read/write head. The SECTOR and SPLIT signals are supplied to a disk controller which uses those signals to control the transfer of data to and from the disk.

摘要： A disc drive includes a base and a disc rotatably attached to the base. A controller for a disc drive uses a system for mapping logical block addresses to actual location on a disc drive stores the number of skipped or defective sectors which occur prior to a target cylinder in a cylinder skip table. The system estimates a starting cylinder location for the selected logical block address. After estimating the cylinder location, a number of skipped defective sectors that have occurred prior to a cylinder start is determined. The starting location of the cylinder is slipped by this amount. A target track and associated head is also determined. Information in the track identification field is used to adjust the actual location on the track and to determine if a track seek to another track is needed.

摘要： During manufacturing of optical disks, mastering equipment inserts marks (“high frequency wobble marks” or “HFWMs”) into the wobble of the groove on optical disks to store data. The presence of a HFWM at a zero crossing of the wobble indicates an active bit and the absence of the HFWM indicates an inactive bit. The zero crossing is, for example, a negative zero crossing. A matched filter is used to detect the shape of the HFWMs. If a HFWM is detected during a wobble cycle, an active bit is saved in a register or a memory. If a HFWM is not detected during a wobble cycle, an inactive bit is saved in a register or a memory. The active and inactive bits may be coded bits that must be decoded to data bits. The data bits include information such as a synchronization mark, a sector identification data, and an error detection code.

摘要： A high level controller for maintaining communication with a host processor via a host processor interface for establishing communication paths between the host processor interface, an internal processor and a plurality of storage means. A first means receives indicia from the internal processor where the indicia specifies one of the communication paths and generates control signals for forming the specific communication path requested. A second means receives the control signals from the first means and forms the requested communication path. A third means is connected to the first and second means for controlling the communication of the system with the host processor interface in accordance with control signals generated by the first means. In this manner various data paths for communication between the host interface, internal processor and a plurality of storage means may be adaptably specified and formed to make optimum use of the system.

摘要： A disk drive architecture controls the transfer of data between a host processor interface and a recording media that includes one or more disk surfaces for storing data. A low-level data controller controls the transfer of data between the disk surfaces and a data buffer. An interface controller controls the transfer of data between the host interface and the data buffer. An arbiter and buffer controller, responsive to data transfer requests from the low-level and interface controllers, arbitrates data storage and retrieval accesses of the data buffer. The low-level and interface controllers operate substantially independent of one another in performing their respective control operations. Consequently, data is transferred bi-directionally through the data buffer at the optimum timing for both controllers.

摘要： A method and system for managing a plurality of defects that may cause an error during a write operation in a write-once data storage disk is provided. A host system sends a write command to a disk drive that contains the storage disk. The process detects any errors that may occur during the write operation. When an error is detected, a “skip list” containing the addresses of physical sectors on the disk that are to be skipped during a read operation is updated, the write operation is suspended, and the process attempts to rewrite the data in another sector. If the rewrite is performed successfully, the write operation continues. Otherwise, the write operation is terminated and the host device is notified. While the disk drive is operative, the skip list is preferably maintained in a buffer memory, but periodically the entries in the skip list are copied to the disk for permanent storage. Before a read operation begins, the skip list is copied from the disk to the memory. When a file is read from the disk, any “skip sectors” that are encompassed within the file are skipped (i.e., the data in those sectors is not read). The method of this invention is particularly useful in supplementing an error correction code, which typically has difficulty dealing with errors of longer duration.
摘要翻译：提供了一种用于管理在一次写入数据存储盘中的写入操作期间可能引起错误的多个缺陷的方法和系统。主机系统向包含存储磁盘的磁盘驱动器发送写入命令。该过程检测在写入操作期间可能发生的任何错误。当检测到错误时，更新包含在读取操作期间被跳过的盘上的物理扇区的地址的“跳过列表”，暂停写入操作，并且该过程尝试重写另一扇区中的数据。如果重写成功执行，写操作将继续。否则，写入操作被终止并且主机设备被通知。当磁盘驱动器可操作时，跳过列表优选地保存在缓冲存储器中，但是周期性地将跳过列表中的条目复制到用于永久存储的磁盘。在读操作开始之前，将跳过列表从磁盘复制到存储器。当从磁盘读取文件时，跳过文件中包含的任何“跳过扇区”（即，这些扇区中的数据未被读取）。本发明的方法在补充纠错码中特别有用，纠错码通常难以处理较长持续时间的错误。
