Abstract: The present invention relates to isolated polypeptides having cellulolytic enhancing activity and isolated polynucleotides encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods for producing and using the polypeptides.

Abstract: An apparatus and method for reading an information signal from a magnetic storage medium using a magnetoresistive (MR) head, and separating a thermal signal component and, if present, a magnetic signal component from the information signal. A signal separation/restoration module eliminates distortion in the magnetic signal component of a readback signal induced by a thermal signal component of the readback signal. A finite impulse response (FIR) filter may be employed in the signal separation/restoration module to eliminate the distortion in the magnetic signal. The signal separation/restoration module may be employed to extract the thermal signal component from the readback signal. In one configuration, an MR head is coupled to an arm electronics (AE) module, having a highpass filtering behavior, and a signal separation/restoration module that includes an inverse filter having a transfer function inverse to that of the effective highpass filter of the AE module.

Abstract: A method and apparatus for accessing a data storage medium having raised and lowered portions indicative of data stored on the medium. Energy is supplied to a sensor which is moved relative to, and in close proximity to, a surface of the medium on which the data in the form of raised and lowered portions is stored. The sensor and the storage medium are moved in relation thereto, such that the sensor remains at a substantially constant fly spacing therefrom. A decrease in temperature of the sensor is detected when it is in proximity to a variation, i.e., a raised portion on the medium. This detected decrease in temperature associated with a raised variation, e.g., asperity, can be used as the basis upon which to detect the data on the data storage medium. The data storage medium may also contain magnetically stored data, such that the surface variations and the magnetic characteristics of the data storage medium can both be utilized to store data thereon.
