Abstract: An apparatus for correcting header information includes a transducer for reading and writing encoded information to a magnetic storage medium. A serial/deserializer provides a deserialized output. Header information from the deserializer is stored in a header storage register. The deserialized header information is also provided to a header error correction circuit. The header error correction circuit provides an output indicating location and value of errors in the header memory. This information is used to correct errors in the header memory. The corrected header information is compared with predetermined header information and used to determine whether subsequent data associated with the header should be written to or read from the magnetic storage medium.

Abstract: A boost-input backed-up uninterrupted power supply provides an uninterrupted output voltage to a load. The backed-up power supply has an input rectifier and filter for converting an input voltage source voltage into at least an unregulated positive dc voltage source, and an unregulated negative dc voltage source. Batteries provide respective positive and negative battery voltages at corresponding positive and negative battery output terminals. A diode isolates the unregulated positive and negative dc voltage sources from their respective battery voltages for unregulated voltage source values equal to or greater than their respective battery voltages and clamps the unregulated dc voltage values to their respective battery voltages in response to loss of the sinusoidal input voltage source. A pair of boost regulators receives power from the unregulated positive and negative dc voltage sources and provide positive and a negative regulated dc voltage with respect to the return.
