Abstract
An apparatus for two-dimensional magnetic recording includes an array reader with a number of magnetoresistive read sensors configured to read data from a storage medium. The magnetoresistive read sensors have a number of connection terminals, with at least one of the connection terminals being shared by more than one of the magnetoresistive read sensors. The apparatus also includes a number of low-noise amplifiers connected to the connection terminals, each configured to amplify a differential signal from a different one of the magnetoresistive read sensors. The apparatus also includes a number of impedance balancing networks connected to a subset of the connection terminals.
