Abstract
This disclosure is related to measurement of latency in data paths. A latency measurement may be accomplished by calculating a roundtrip write-to-read latency based on generating a write signal and receiving a read signal approximately simultaneously. The read signal may be based on a coupling between a write element and read element. A device setting may then be adjusted based on the calculated roundtrip write-to-read latency. Further, a read/write mechanism that is used to write user data to and read user data from a data storage medium may be used to determine the roundtrip write-to-read latency. Even further, the roundtrip write-to-read latency may be determined in real-time as the data storage device is in operation.
