Abstract: Aspects of the present disclosure generally relate to magnetic recording heads of magnetic recording devices. A magnetic read head includes a first pinning layer magnetically oriented in a first direction, and a second pinning layer formed above the first pinning layer and magnetically oriented in a second direction that is opposite of the first direction. The magnetic read head includes a rear hard bias disposed outwardly of one or more of the first pinning layer relative or the second pinning layer. The rear hard bias is magnetically oriented to generate a magnetic field in a bias direction. The bias direction points in the same direction as the first direction or the second direction. The magnetic read head does not include an antiferromagnetic (AFM) layer between a lower shield and an upper shield.

Abstract: The present disclosure generally related to a two dimensional magnetic recording (TDMR) read head having a magnetic tunnel junction (MTJ). Both the upper reader and the lower reader have a dual free layer (DFL) MTJ structure between two shields. A synthetic antiferromagnetic (SAF) soft bias structure bounds the MTJ, and a rear hard bias (RHB) structure is disposed behind the MTJ. The DFL MTJ decreases the distance between the upper and lower reader and hence, improves the area density capacity (ADC). Additionally, the SAF soft bias structures and the rear head bias structure cause the dual free layer MTJ to have a scissor state magnetic moment at the media facing surface (MFS).

Each column of nodes is coupled to one of n first conductive lines, and each row of nodes is coupled to one of m second conductive lines. Each node of the m rows and n columns of nodes includes a spin orbit torque-based spin torque oscillator circuit configured to oscillate at a corresponding intrinsic frequency. The spin orbit torque-based spin torque oscillator circuits are configured to generate m output signals at the m second conductive lines upon application of n input signals to corresponding n first conductive lines. The n input signals correspond to an n-element input vector, and each input signal includes a corresponding input signal frequency. Each of the m output signals include frequency domain components at the input signal frequencies.

Abstract: Computing devices, such as mobile computing devices, have access to one or more image sensors that can capture images with multiple subjects. Some of these subjects may be known to the user capturing an image with the image sensor. The user may prefer to have the captured image data be optimized around the known subjects. Low-power, fast-response machine learning logic can be configured to allow for the generation of a plurality of inference data. This inference data can be utilized along with other sensor data, such as a motion sensor, for the generation of one or more image sensor configuration changes that may be implemented to optimize the subsequent capture of image data. This cycle of image data analysis, image sensor optimization, and subsequent capture can continue multiple times until a threshold of optimization or time is met. The captured image data optimized around the known subjects is then stored.
