摘要： A flying-type magnetic head includes a magnetic head chip composed of a pair of cores, each having a metallic magnetic thin film thereon which faces a magnetic gap. The magnetic chip is inserted and fixed in a slit provided in a non-magnetic slider at the outlet side of a magnetic recording medium generating airflow across an air bearing. The back of the slider is fixed to a gimbal in such a manner that a flying plane portion of the magnetic head faces the magnetic recording medium. The height at the flying plane portion of the slider is structurally controlled such that the height where the back of the slider is fixed to the gimbal differs by 20 nm or less with respect to the height thereof when the back of the slider is not fixed to the gimbal. The magnetic head chip may be composed of a pair of non-magnetic cores, each of which has a metallic magnetic thin film deposited thereon.

摘要： A magnetoresistive (MR) head for sensing magnetic data recorded on a magnetic recording medium with high track density and high linear density includes a magnetoresistive conductive layer (MR layer), a soft magnetic layer (SAL) for transversely biasing the MR layer and hard magnet layers for longitudinally biasing and controlling magnetization in the central sensing regions of the MR layer and the SAL. The longitudinal bias applied to the SAL is less than that to the MR layer so that a sensing current produces an effective magnetic field to saturate the SAL transversely. So, magnetization in the MR layer is kept at an angle of 40 to 45 degrees to easy magnetization direction of the MR layer and the improved reproducing output is obtained.

摘要： The present invention provides drug carriers having high heating efficiency by high-frequency dielectric heating in a state of being selectively accumulated in a target site. The drug carriers each consist of a drug, magnetic fine particles, and a shell containing the drug and the magnetic fine particles. The shell has an outer diameter in a range from 10 nm to 200 nm. The magnetic fine particles having an average particle diameter of d has a standard deviation σ of particle diameter distribution satisfying 0.8d>σ>0.4d. The magnetic fine particles contained in the individual drug carriers generate hysteresis heat due to high-frequency dielectric heating by irradiation of a high-frequency magnetic field.

摘要： A magnetoresistive (MR) transducer is disclosed in which an exchange coupled anisotropy field is provided by an antiferromagnetic NiMn alloy in contact with the MR alloy. Improved exchange coupling is achieved using an MR layer and adjacent NiMn exchange coupling layer which have substantially fcc structure and a preferred {111} crystalline orientation. The exchange bias field is observed to correlate strongly with the structural order of the films. A preferred method of fabricating the MR transducer enhances the structural order of the layers during growth, thereby reducing a post-deposition anneal typically required in such processes. The preferred fabrication process further provides greater predictability and control over the resulting exchange coupling.
