Abstract
A method comprises manufacturing a read/write head for a disk drive; then testing the read/write head; and then mounting the read/write head to a suspension only after the testing step indicates that the read/write head is not defective. The testing may be performed by writing information to and reading information from a non-disc shaped media paddle that is caused to move back and forth with respect to the read/write head in oscillatory fashion.
