Abstract
Data detection method and apparatus in a data storage device are provided. The data detection apparatus includes: a Random Access Memory (RAM) updating device for obtaining the average characteristic of the equalization signal z.sub.k from the symbol data a.sub.k and storing and updating the obtained result; threshold value calculator for calculating an optimal threshold value with respect to each data pattern from the average characteristic of the equalization signal z.sub.k updated in the RAM updating device; and a detector for detecting the value of the symbol data a.sub.k by comparing the equalization signal z.sub.k with the threshold value calculated in the threshold value calculator. Thus, a signal is detected by obtaining an average characteristic of a signal according to a data pattern and then using an optimal threshold value to detect the signal so that a signal having considerable non-linear distortion and a Direct Current (DC) offset can be reliably detected.
