  • Anode for lithium secondary battery and lithium secondary battery including the same
    Patent number: 11929495
    Abstract: In some implementations, the anode includes a current collector, a first anode mixture layer formed on at least one surface of the current collector, and a second anode mixture layer formed on the first anode mixture layer. The first anode mixture layer and the second anode mixture layer include a carbon-based active material, respectively. The first anode mixture layer includes a first binder, a first silicon-based active material, and a first conductive material. The second anode mixture layer includes a second binder, a second silicon-based active material, and a second conductive material. Contents of the first conductive material and the second conductive material are different from each other with respect to the total combined weight of the first anode mixture layer and the second anode mixture layer. Types of the first silicon-based active material and the second silicon-based active material are different from each other.

  • Hard disk drive and method for controlling flying height of magnetic head thereof
    Patent number: 9177583
    Abstract: There is disclosed a hard disk drive and a method of controlling a flying height of a magnetic head of the hard disk drive. A method of controlling a flying height of the magnetic head in a hard disk drive according to an embodiment of the present invention may include (a) providing a FOD sensitivity through a FOD test; (b) reading a preamble signal of a servo pattern; (c) calculating a flying height of the magnetic head from the preamble signal; and (d) applying FOD power for adapting the flying height of the magnetic head to a target flying height of the magnetic head based on the calculated flying height of the magnetic head and the FOD sensitivity.
