Abstract: Methods and systems for detecting reliability defects on a wafer are provided. One method includes acquiring output for a wafer generated by an inspection system. The method also includes determining one or more geometric characteristics of one or more patterned features formed on the wafer based on the output. In addition, the method includes identifying which of the one or more patterned features will cause one or more reliability defects in a device being formed on the wafer based on the determined one or more characteristics.

Abstract: The present invention provides a method and apparatus for providing position detection using a unique binary sequence encoded in indexing bits stored in servo wedges. The present invention generates a unique binary sequence (UBS) code and stores the bits of such a code in the indexing bits of the servo wedges. The bits are read from the servo wedges and used to provide unique identification of head position. Each servo wedge and each data field can be uniquely identified, even servo wedges and data fields under different heads. The present invention may be used to provide initial position detection, position verification during normal operation, and position verification upon head switching. When used for position verification, the present invention uses a confidence block to determine the confidence level with which the head is believed to be correctly positioned.

Abstract: A disk drive having error detection and correction capability includes a dedicated finite field processor for performing corrections and for generating software syndromes for miscorrection detection. The processor operates over a finite field under program control and performs parallel finite field multiplication and addition operations in a single execution cycle.

Abstract: An intelligent disk drive employing a controller which performs high speed error correction and miscorrection detection using a finite field processor. The error correction code is defined over a finite field and the error detection code is defined over an extension field of the finite field. The finite field processor performs calculation over both the finite field and extension field to provide high speed error correction and correction validation.

Abstract: An intelligent disk drive having error detection and correction capability employs an embedded error correction controller with a pipelined architecture for performing error correction under program control. The pipelined architecture provides parallel operand fetching and instruction execution for high speed operations during error correction.

Abstract: An intelligent disk drive includes a controller which embeds user data address information into error correction code check symbols written to the data storage disk. The address information is not written to disk, but address errors are detected by decoding the error correction code check symbols during read operations. Disk space is saved while maintaining robust address error detection.
