Abstract
In the present disclosure, a method of operating a data storage apparatus is provided. The method includes writing a data signal into a portion of a data layer in a recording medium of a data storage apparatus. The method further includes determining a data layer coupling interference value arising due to interference from the data layer provided in between a sensor head and a servo layer of the recording medium in reading servo data, the data layer coupling interference value determined based on the data signal. The method further includes writing the data layer coupling interference value onto the recording medium. A corresponding data storage apparatus is provided.
