Method and circuit for decoding a sample of a signal read from a storage medium to obtain a physical address of data on the storage medium

A circuit comprising:

• a converter configured to sample a signal read from a storage medium to generate a sample, wherein the signal includes a physical address of data read from a track on the storage medium;
• a timing control device configured to generate a clock signal based on a deviation of the track from a reference line;
• a first scaling device configured to generate a first scale factor based on the clock signal;
• a first multiplier configured to multiply the sample by the first scale factor to generate a first scaled sample;
• a first integrator configured to integrate the first scaled sample over a period of the clock signal to generate a first resultant value;
• a comparator configured to compare the first resultant value to a threshold to generate an output, wherein the output indicates whether no phase imperfection exists in the first scaled sample;
• and
• a decoder configured to, based on the output of the comparator, decode the first resultant value to obtain the physical address of the data.
