Apparatus and methods are described for identifying desired data recorded in a magnetic media based on the density in which the data is recorded in the media. In one embodiment the invention includes a first magnetic reading head connected to a first intermediate network, second magnetic reading head connected to a second intermediate network and a logic unit connected to the first and second intermediate networks, where the logic unit is configured to compare the rates at which flux transitions occur at the first and second reading heads.
