摘要： An ATA-compatible drive interface with error correction and detection capabilities is disclosed. Being fully ATA backward compatible, this interface functions with the same physical cable and connectors as current ATA systems, employs bus drivers that are the same as or backward compatible with those provided by earlier versions of the ATA standard and uses signals with cable signal transitions no faster than those presently seen by current ATA devices. The error detection feature indicates when a data block is erroneously transferred between the device and host; the error correction feature identifies the words transmitted in error and corrects those words on the receiving side of the interface. So that ATA backward compatibility is maintained, the data integrity checking feature does not require additional words in a data transfer, and the data correction feature does not require new data transfer protocols or additional data transfer overhead. Also disclosed are interface circuitry and a new ATA-compatible transfer mode capable of transferring data at 40 MB/sec, the rate supported by local bus adapters for disk drives. Given the physical limits of the ATA cables and connectors, the error correction and detection features are especially useful for correcting data words corrupted during high-speed transmission; however, error correction and detection can also operate independently of the fast transfer mode. Consistent with full backward compatibility, a hard drive configured with the new, fast, error-correcting interface is transparently functional when plugged into a current ATA adapter provided by a legacy computer system.

摘要： A magnetic disc storage system includes a rotating magnetic disc and a read/write transducer positioned proximate a recording surface of the magnetic disc for reading and writing information on the recording surface. Data stored on the recording surface is altered based upon the address of the data. During readback, a pseudorandom number generator receives a desired address as a seed input and provides a pseudorandom number output. An XOR gate provides an XOR output in response to the pseudorandom number output and the readback signal from the read/write transducer. An error detection circuit provides a decoded data output and an error flag output in response to the XOR output. An error during readback indicated by the error flag output is indicative of an incorrect address of the readback signal in comparison to the desired address. During a write operation, data is provided to an error detector encoder circuit which provides an encoded data output to an XOR gate. A pseudorandom number generator receives the address of the data as a seed input and provides a pseudorandom number to the XOR gate. The output of the XOR gate is written on the surface of the magnetic disc by the read/write transducer.

摘要： A snap ring having improved retention characteristics is configured for use inside a cylindrical cavity. The cavity includes a retention device having a retention surface forming an obtuse angle with the cavity wall. As an axial load is applied to the snap ring, it moves along the retention surface, thereby experiencing a reduction in diameter. The snap ring includes a circumferential discontinuity defined by two generally radial planar surfaces, or ring ends. The discontinuity is configured such that the ring ends will abut one another before the snap ring diameter is reduced beyond the retaining diameter.
