Servo track encoding and decoding

A method comprising:

• decoding a first value based on a first code to obtain a decoded first value, wherein the decoded first value is associated with a first plurality of bits that corresponds to a most significant bits of a servo track;
• and
• decoding a second value based on a second code to obtain a decoded second value, wherein the second value is associated with a second plurality of bits that corresponds to a least significant bits of the servo track, wherein the second code is a de-Gray code,
• wherein a servo track address is obtained from the decoded first value and the decoded second value,
• wherein the second value repeats itself after a certain number of servo tracks based on the second code and its associated run length.

A system comprising:

• a memory component configured to store information;
• a processor configured to process information and further configured to control operation of other components;
• an encoder controlled by the processor, wherein the encoder is configured to encode a first portion of a servo track with a first code resulting in a first encoded value and wherein the encoder is configured to encode a second portion of the servo track with a second code resulting in a second encoded value, wherein the second code has a run length associated therewith, wherein the first encoded value and the second encoded value result in a Gray code and wherein each bit of the Gray code remains constant for at least a number of tracks corresponding to the run length;
• a head configured to write the first encoded value and the second encoded value on a media, wherein the head is further configured to read the first encoded value and the second encoded value from the media;
• and
• a decoder controlled by the processor, wherein the decoder is configured to decode the first encoded value and further configured to decode the second encoded value, wherein the processor is further configured to determine a servo track address from the decoded first value and the decoded second value.
