Abstract:
A method of manufacturing a disk drive comprising a disk having first and second magnetic surfaces, and first and second read/write transducers for writing information on and reading information from said first and second magnetic surfaces, said method comprising:(a) determining a track width performance characteristics to be measured for a read/write transducer to be used in the disk drive;(b) establishing a plurality of performance groups, each performance group having an associated range of values of the track width performance characteristic;(c) measuring the track width performance characteristic determined in step (a) of an individual read/write transducer to determine the measured value of the track width performance characteristic;(d) comparing the measured value of the track performance characteristic of the individual read/write transducer measured in step (c) to determine if the measured value of the track width performance characteristic is within one of the performance groups established in step (b);(e) repeating steps (c) and (d) until two individual read/write transducers are found which both have a track width performance characteristic value which is common to one of the performance groups established in step (b); and(f) assembling the disk drive using one of the individual read/write transducers found in step (e) as the first read/write transducer of the disk drive, and using the other of the individual read/write transducers found in step (e) as the second read/write transducer of the disk drive.
