An enhanced oscillation test for detecting off track writing associated with a read/write head writing, on a magnetic media, a measurement track. Once the measurement track is written, a series of seek, write, and read operations is performed, e.g., between various origin tracks and the tracks adjacent to the measurement track, in order to detect any off track write problems. If a measurement track read operation fails a certain number of times, then an error code is generated which indicates an off track write problem.
