Disk pack swap process for evaluating magnetic recording performance

A method for performing tests on designs of magnetic media, wherein a read/write head and a recording channel remain constant, such that results are consistent with those expected when said magnetic media is assembled into a final product, said method comprising:

• recording a first set of baseline measurements from a first magnetic media utilizing said read/write head and said recording channel;
• removing said first magnetic media from an assembly comprising said read/write head and said recording channel and replacing it with a second magnetic media;
• and
• collecting measurements from said second magnetic media utilizing said read/write head and said recording channel, wherein said measurements are compared with said baseline measurements to determine noise associated with the read/write head and said recording channel which maintains consistent performance of said read/write head and said recording channel with those expected when said magnetic media is assembled into a final product.

A method of swapping magnetic media and maintaining consistency of read/write head and a recording channel performance when testing magnetic media designs, comprising:

• recording a first set of baseline measurements from a first magnetic media utilizing said read/write head and said recording channel;
• removing said first magnetic media from an assembly comprising said read/write head and said recording channel and replacing it with a second magnetic media;
• and
• collecting measurements from said second magnetic media utilizing said read/write head and said recording channel, wherein said measurements are compared with said baseline measurements to determine noise associated with said read/write head and said recording channel which maintains consistent performance of said read/write head and said recording channel when testing a plurality of magnetic media designs.
