    Abstract: A method of controlling a filter coefficient of a continuous time filter of a data storage device is provided. The method of controlling filter coefficient includes positioning a magnetic head at a first reference height from surface of a magnetic disk and outputting a plurality of CSM values by measuring a channel state from a read signal output from the magnetic head when changing a cut-off frequency of the continuous time filter, positioning the magnetic head at a second reference height spaced from the first reference height and measuring a bit error ratio from a read signal output from the magnetic head positioned at the second reference height according to at least one CSM value selected among a plurality of CSM values, and controlling a filter coefficient value to determine a cut-off frequency of the continuous time filter according to a measured bit error ratio.

    Abstract: A method for making n-type semiconducting diamond by use of CVD in which n-type impurities are doped simultaneously with the deposition of diamond. As the n-type impurities, an Li compound and a B compound, both, are used at once. After doping, a diamond film thus obtained is etched to peel off its surface. The n-type semiconducting diamond is superior in specific resistivity, 10.sup.-2 .OMEGA.cm or less.
