    摘要: A medium, system, and method are disclosed for a common data storage medium depression depth. An optical data storage medium comprises a plurality of spacer layers and data surfaces. A wavelength for a radiation beam such as the emission of a laser diode is identified. The index of refraction for a first spacer layer or substrate is also identified. The substrate is configured to transmit the radiation beam. The index of refraction of a second spacer layer that is configured to transmit the radiation beam is also identified. A depression depth for a plurality of pits for ROM media, or sector headers for recordable media, or grooves for recordable media on each data surface is substantially equal to the radiation beam wavelength divided by four times the average of the indexes of refraction of each spacer layer. In one embodiment, the average is an arithmetic mean of the indexes of refraction. In an alternate embodiment, the average is a harmonic mean of the indexes of refraction. The average may also be a geometric mean of indexes of refraction.

    摘要: A method and apparatus to identity SPAM emails is disclosed. The method sets a misspelling rejection ratio. Upon receipt of an email comprising (X) words, the method determines the number (Y) of misspelled words comprising that email. The method then calculates a misspelling ratio by dividing (Y) by (X), and then determines if the misspelling ratio is greater than or equal to the misspelling rejection ratio. If the method determines that the misspelling ratio is greater than or equal to the misspelling rejection ratio, then the method reports the email as SPAM. In certain embodiments, the detection of words used to trigger the rejection of SPAM is based on a fuzzy search of alternate spellings. These alternate spellings may come from a spell checker.

    摘要: A system, a method, and article of manufacture are employed to clean the input/output transducers on tape drives, verified by the tape drives reading alphanumeric information from data tracks and servo tracks of a cleaner tape. An aggressive cleaning frontcoat section of the cleaner tape can be used to provide additional cleaning action, and the cleanliness of the data read elements, data write elements, and the servo heads. A less-abrasive cleaning section may be used to clean less difficult types of contaminants. In this manner, the cleanliness of the data read elements, the data write elements, and the servo heads can be verified. A cleaning section may also be used as a leader section of a self-characterization section. Alternatively, a magnetic data tape section may be included for self-characterization.
