Abstract: Certain exemplary aspects of the present disclosure are directed towards apparatuses and methods which mitigate the effect of speaker vibration on a disc drive. Audio associated with a speaker output is detected and triggers the generation of an output signal indicative of speaker vibration associated with such an audio output of a speaker. A magnetoresistive transducer of the disc drive is positioned relative to a storage medium based on the output signal, a target data storage location in the storage medium from which data is to be accessed via the positioning, and the position of the transducer. The output signal mitigates the effect of the speaker vibration on the transducer.

Abstract: A data storage device includes a main storage memory and a non-volatile cache memory system. The non-volatile cache memory system comprises a master device, a first slave device communicatively coupled to the master device, the first slave device comprising a first non-volatile memory, and a second slave device communicatively coupled to the master device, the second slave device comprising a second non-volatile memory of a different type than the first non-volatile memory. The data storage device also includes a controller communicatively coupled to the main storage memory and to the non-volatile cache memory system, the controller is configured to, upon a power loss to the data storage device, store volatile data into the non-volatile cache memory system.
