  • Publication number: 20240135962
    Abstract: According to one embodiment, a magnetic head includes first and second magnetic poles, a conductive part, an element part, and first to fourth terminals. The conductive part is electrically insulated from the first and second magnetic poles. The first and second terminals are electrically connected to the conductive part. The element part is provided between the first and second magnetic poles and electrically connected to the first and second magnetic poles. The element part is conductive. The third terminal is electrically connected to the first magnetic pole. The fourth terminal is electrically connected to the second magnetic pole. A first magnetic pole temperature in a first state is higher than a second magnetic pole temperature of the second magnetic pole in the first state. A first current is supplied between the first and second terminals in the first state.

  • Publication number: 20240070553
    Abstract: According to one embodiment, a data processing device includes an acquisitor, and a processor. The acquisitor is configured to acquire a first acquired data and a first other data. The processor is configured to perform a first evaluation index derivation operation deriving a first evaluation index from a plurality of first regression labels and a plurality of first synthetic regression labels. The first regression labels are derived from a plurality of first machine learning models. The first machine learning models are derived from a plurality of first sample data. The first synthetic regression labels are derived from a plurality of first synthetic machine learning models. The first synthetic machine learning models are derived from the first sample data and the first acquire data by a first transfer leaning. The first sample data are derived from the first other data or a first conversion other data.

  • Publication number: 20240046959
    Abstract: According to one embodiment, a magnetic head includes a first magnetic pole, a second magnetic pole, and a stacked body. The first magnetic pole includes a first face and a second face crossing the first face. The second face includes a first face region continuous with the first face. The second magnetic pole includes a third face and a fourth face crossing the third face, and the fourth face includes a second face region that is continuous with the third face. The first face and the third face are along the third direction. The stacked body is provided between the first face region and the second face region. The stacked body includes a first magnetic layer, and a second magnetic layer provided between the first magnetic layer and the second face region. The second magnetic layer includes a second magnetic layer face facing the second face region.

  • Publication number: 20230334377
    Abstract: According to one embodiment, a data processing device includes a processor. The processor is configured to generate a first machine learning model based on a first generated data based on the first acquired data and a first other acquired data in the first operation. The first other data includes a first other feature value matrix with Np rows and D1 columns and a first other label with Np rows. The Np is an integer of 2 or more. The D1 is an integer of 1 or more. The first acquired data includes a first feature value matrix with N1 rows and D1 columns and a first acquired label with N1 rows. The first generated data includes a first generated matrix with (Np+N1) rows and (3√óD1) columns and a first generated label with (Np+N1) rows. (Np+N1)/D1 is 250 or more.
