Abstract
A computer-implemented method for screening a multichannel head, according to one embodiment, includes measuring a channel signal to noise ratio value for each read transducer over a plurality of sense currents, wherein each transducer is one of a plurality of transducers in a multichannel head. The measured channel signal to noise ratio values are compared to a specification of a pre-defined value. The multichannel head is dispositioned to enable the multichannel head to perform to the specification of the pre-defined value, if possible.
