Patent ID: 8837065

Claim:
A system for performing fast measurement of a channel performance metric and off-track recording capability in shingled magnetic recording, the system comprising: a test platform configured to receive, support, and rotate a disk configured for magnetic information storage; a magnetic transducer configured to write to, and read from, the disk; a memory; a processor coupled to the memory, the magnetic transducer, and the test platform, the processor configured to: write a plurality of shingled tracks on the disk; measure an off track read capability (OTRC) of each of the plurality of shingled tracks; determine radial endpoints of the measured OTRC for each of the plurality of shingled tracks; determine an approximate radial center for each of the plurality of shingled tracks based on the respective OTRC radial endpoints; and measure a channel performance metric at a range centered around each of the approximate radial center for each of the plurality of shingled tracks.
