Servo zone transition optimization for magnetic disk recording devices

A method comprising:

• assessing at least one operation of a read/write head of a disk drive;
• formatting, based at least in part on the assessing of the read/write head, a disk surface of the disk drive with a first servo zone a second servo zone, and an overlap region extending between a start point of the second servo zone and an end point of the first servo zone, a start of the overlap region being towards an inner diameter (ID) of the disk surface, and an end of the overlap region being towards an outer diameter (OD) of the disk surface, the disk drive performing internally the formatting of the disk surface or the assessing of the at least one operation of the read/write head of the disk drive, or both, a width of the overlap region being based at least in part on a servo sector error rate of the read/write head determined by the assessing of the read/write head.
