ABSTRACT:
Embodiments of the present invention relate to systems, methods, and computer readable media for storing data on a rotatable storage medium. A hard drive having a rotatable storage medium is configured with different environmental tolerance characteristics for different sides of the rotatable storage medium. A first side is configured to have a higher tolerance to environmental factors such as shock and temperature by modifying features of the first side of the media and the read/write mechanism configured to interact with the first side. A second side of the storage medium is configured with lower environmental tolerances, thus allowing for higher performance. This configuration enables the hard drive to perform at a higher level of performance when facing less adverse environmental conditions while still remaining functional when facing more adverse environmental conditions.
