摘要: According to one embodiment, a magnetic disk device includes a magnetic disk, a motor, a magnetic head, and a controller. A first area, and a second area located on an inner diameter side of the first area are provided in the magnetic disk. The motor rotates the magnetic disk. The controller receives a write command. In a case where a first position that is a position designated as a write destination of data by the write command is included in the first area, the controller writes the data to the first position by the magnetic head while rotating the magnetic disk at a rotational speed of a first value. In a case where the first position is included in the second area, the controller writes the data to the first position by the magnetic head while rotating the magnetic disk at a rotational speed of a second value larger than the first value.

摘要: According to one embodiment, a magnetic recording device includes a magnetic head and a controller. The magnetic head includes first and second magnetic poles, a magnetic element provided between the first and second magnetic poles, and first and second terminals. The controller is configured to perform a recording operation. In the recording operation, the controller is configured to supply a recording current to the coil while applying an element voltage not less than a first voltage and not more than a second voltage between the first terminal and the second terminal. A differential resistance of the magnetic element when a positive applied voltage applied between the first terminal and the second terminal is changed while the recording current is supplied to the coil becomes a first peak when the applied voltage is the first voltage.

摘要: A frequency data transmission and encryption system comprises a transceiver module. The transceiver module is configured to receive and transmit computer-readable instructions via transmission signals comprising two distinct signals having a first frequency and a second frequency different than the first frequency. The transceiver module is further configured to convert the two distinct signals to and from a first set of computer-readable instructions based on the first frequency using a first conversion method, and a second set of computer-readable instructions based on the second frequency using a second conversion method different from the first conversion method.

摘要: The present disclosure relates to an information processing device and method that enables simultaneous use of a plurality of video components for one object using a scene description. In an extension for the 3D object video defined in a material layer of a scene description file, a component index having a different value for each of video components is set to a video component included in the 3D object video. In addition, the video component is stored in a corresponding buffer on the basis of the component index, the video component is acquired from the buffer on the basis of the component index, and a display image is generated using the acquired video component. The present disclosure can be applied to, for example, an information processing device, an information processing method, or the like.

摘要: Methods and devices are described for reducing the audible effect of pre-responses in an audio signal. The pre-responses are effectively delayed by employing a digital non-minimum-phase filter, which includes a zero lying outside the unit circle in its z-transform response. This zero is not paired with another zero at a reciprocal position inside the unit circle, as this would linearise the phase modification. The filtering can introduce a greater group delay at the pre-response frequency than at a low frequency, such as 500 Hz or even 0 Hz. The technique can be used to reduce pre-responses in an existing audio signal and also to pre-empt pre-responses that would be introduced to the audio signal by subsequent processing.

摘要: According to one embodiment, first, a frequency to be corrected by an MA additional filter is specified based on a head position error spectrum and a multi-rate sensitivity characteristic, in a state before the MA additional filter is added. Then, a candidate in which a peak of the multi-rate sensitivity characteristic is equal to or less than a threshold value and a head position error is minimized is determined as the MA additional filter to be used, in a state in which each of a plurality of candidates of the MA additional filter is added.
