Multi-revolution hard disk drives with reduced servo overhead

A hard disk drive comprising:

• a spinning magnetic media disk having a servo pattern that includes reduced overhead servo fields, the servo pattern comprising a series of servo wedges, each servo wedge extending radially from an inner portion of the magnetic media disk to an outer portion of the magnetic media disk, and wherein only one of the servo wedges includes full servo track identification information;
• a recording head configured to write data to and read data from the spinning magnetic media disk;
• and
• a controller configured to control the recording head and to operate the hard disk drive in a multi-revolution mode in which multiple revolutions of the spinning magnetic media disk are used for read and/or write operations, and configured to utilize the multiple revolutions to compensate for the reduced overhead servo fields.

A method for use with a hard disk drive that includes a magnetic media disk, the method comprising:

• determining correction information for inclusion in servo data fields;
• writing a portion of the servo data fields in a servo pattern on the magnetic media disk, the portion of the servo data fields excluding a remaining portion of the correction information;
• storing the remaining portion of the correction information in a memory off of the magnetic media disk;
• and
• using information retrieved from the servo pattern on the magnetic media disk and the remaining portion of the correction information during operation of the hard disk drive.
