主权项 1. A method for reading data from a storage medium using a reader, wherein the reader comprises at least one reader head, the method comprising: reading a first signal with a reader head of the reader at a pre-determined position of the storage medium, wherein the storage medium comprises a plurality of tracks written using shingled magnetic recording; reading a second signal with a reader head of the reader at the pre-determined position of the storage medium; determining a trigger signal directly from a readback signal from the storage medium, wherein the trigger signal is a pre-written low-frequency signal at a beginning of a data track, which includes the pre-determined position; and determining a mechanical jitter free signal based on the trigger signal; and determining data stored at the pre-determined position of the storage medium based on (i) an average of the first signal and the second signal, (ii) and the mechanical jitter free signal.
