Abstract
A topography detection mechanism may measure surface height of a side read/write track while the read/write head is interacting with a current read/write track. A memory may store the measured surface height.
Claims30
A system for controlling a read/write head that interacts with read/write tracks on a rotating information storage surface, the system comprising:
- a topography detection mechanism configured to measure surface height of a side read/write track when the read/write head is interacting with a current read/write track;
- and
- a memory configured to store indications of the measured surface height.
A non-transitory computer-readable storage medium comprising program code for performing a method for controlling a read/write head that interacts with read/write tracks on a rotating information storage surface, the method comprising:
- measuring surface height of a side read/write track when the read/write head is interacting with a current read/write track;
- and
- storing indications of the detected measured surface height in a memory.
