Abstract
A read channel (18) is provided for use in a mass storage system. The read channel (18) includes a plurality of circuit modules and an error estimation circuit (50). The plurality of circuit modules receive an analog data signal from a disk/head assembly (12) and condition the signal to provide a digital data signal. The error estimation circuit (50) receives an analog signal from one of the plurality of circuit modules and analyzes the analog signal. The error estimation circuit (50) provides digital error signal (94) and digital level estimation signal (96) as a result.
