Recording medium, a data storage apparatus and a method of preparing a recording medium

A recording medium comprising:

• a first annular servo track provided on a first layer of the recording medium;
• and
• a second annular servo track provided on the first layer of the recording medium and adjacent to the first annular servo track,
• wherein
• the first annular servo track is provided with a first bit pattern,
• the second annular servo track is provided with a second bit pattern, and
• a bit randomization portion is provided in an annulus formed by an exterior perimeter of the first annular servo track and an interior perimeter of the second annular servo track.
