Title: Gain compensating device and method for correcting thermal asperity
Inventor: CHERN JENN-GANG
IPC: G11B27/36
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To improve chip performance by detecting a thermal asperity phenomenon and reducing the input resistance value of a read channel amplifier and also increasing the gain of the read channel amplifier to reduce a signal distortion. SOLUTION: A preamplifier 500 is connected to a read channel amplifier (VGA) 504 via a pair of coupling capacitors 502. A thermal asperity phenomenon detector 508 changes the input resistance value of the VGA: 504 by sending a signal to a variable shunt resistor 506 and changing the resistance value of the resistor 506 in order to compensate a thermal asperity phenomenon. Moreover, the detector 508 transmits a signal to a gain compensating DAC: 510 which outputs and analog signal changing the gain of the VGA: 504 by an amount corresponding to a gain change due to the resistor 506. Analog outputs of a feedback gain DAC: 520 and the gain compensating DAC: 510 are added in an adding connection part 522 to be inputted to the VGA: 504.
