  • Data storage medium with optimized servo format
    Patent number: 7405893
    Abstract: A data storage medium and data storage system with improved efficiency of formatting are provided. One illustrative embodiment of the present invention pertains to a data storage medium. The data storage medium includes a first zone having servo information written with a first frequency, a second zone having servo information written with a second frequency, and a guard band disposed between the first zone and the second zone. The use of different frequencies in different zones contributes to optimizing the properties of the data storage medium, and the guard band contributes to optimizing the usage of the different zones.

  • Head polarity detection algorithm and apparatus
    Patent number: 7133227
    Abstract: A method of determining and monitoring head polarity of data heads comprises performing a head polarity detection routine. The head polarity detection routine comprises the step of setting a read gate period duration to a first value. The routine also comprises searching for a good address mark signal during a first read gate period with a channel polarity set to a first polarity. The routine further comprises identifying a polarity of a data head based upon the channel polarity when the good address mark is detected.
