Abstract: Systems and methods are disclosed for electronic device power consumption grading. In some examples, similar electronic devices may consume different amounts of power due to variations in components of the electronic devices. The components can include electrical components (e.g., discrete circuits, integrated circuits, etc.), mechanical components (e.g., motors, traces, etc.), electro-mechanical components (e.g., switches, motors, piezoelectric devices, etc.). Power consumption information for specific components can be determined and a power consumption grading for the specific electronic device can be determined from the power consumption information. A user may then utilize the power consumption grading to optimize a usage of the electronic device.

Abstract: A storage device includes a controller that determines a degree of data degradation for a data track targeted by a pending read command and sets a head/media clearance parameter for execution of the read command based on the determined degree of data degradation for the data track, the head/media clearance parameter providing for a greater head-media separation when the determined level of degradation is lower than when the determined level of degradation is higher.

Abstract: A method includes receiving a write command including data to be stored and a logical block address associated with the data. The method includes selecting, from a pre-defined plurality of cooling zones of a data storage chassis, a cooling zone in which to store the data. The method further includes writing the data to a data storage device in the cooling zone.

Abstract: A data storage system includes a logical space having logical block addresses (LBAs) divided into non-overlapping LBA ranges, and a physical space having pairs of physical bands. The system also includes a map in which first successive alternate LBAs of each different one of the non-overlapping LBA ranges are mapped to successive adjacent physical blocks of a first physical band of each different pair of the pairs of physical bands, and second successive alternate LBAs of each different one of the non-overlapping LBA ranges are mapped to successive adjacent physical blocks of a second physical band of each different pair of the pairs of physical bands. A controller employs the map to concurrently read data from a first physical block of the first physical band of one pair of physical bands and from a first physical block of the second physical band of the same pair of physical bands.

Abstract: A method includes detecting noise in a laser output of a heat assisted magnetic recording device. The noise is converted into an electrical signal including a numerical value. A least significant digit of the numerical value is selected. The least significant digit is concatenated with another least significant digit from another detecting of another noise in another laser output to form a number.

Abstract: A hard disk drive includes a first actuator and a second actuator. The first actuator is coupled to a first slider, which includes a first read transducer and a first write transducer. Both the first read transducer and the first write transducer are positioned away from a first longitudinal centerline of the first slider. The second actuator is coupled to a second slider, which includes a second read transducer and a second write transducer. Both the second read transducer and the second write transducer are positioned away from a second longitudinal centerline of the second slider.
