摘要： A magneto-resistive (MR) head includes protection from electrostatic discharge without introducing additional processing steps. The MR sensor comprises a soft film biased (SFB) magnetic read sensor sandwiched between two high resistivity magnetic materials. The MR sensor is located between two MR shields wherein each MR shield is connected to an MR sensor ground signal lead by a resistor. The resistor is constructed from the high resistivity magnetic material such that the resistor is deposited at the same process step as the MR sensor.

摘要： A shorted dual MR head (70) which is magnetically shielded for the purpose of isolating the dual MR head from extraneous magnetic fields and from long wavelength recorded signals which could cause nonlinear distortion of the dual MR head but not shielded for the purpose of improving linear resolution. The magnetic shields (10,12) do not significantly affect linear resolution of the dual MR head and can be spaced apart from the dual MR head over a wide range of separation distances limited by factors other than the characteristic bit length of the magnetic signal to be resolved. In one embodiment, at least one shielding element for the dual MR head can be one of the poles or other components of an inductive record head and, together, the two heads can form an integrated thin-film inductive record/MR reproduce head assembly.
摘要翻译：用于将双MR磁头与外部磁场和长波长记录信号隔离的短路双MR磁头，其可能导致双MR磁头的非线性失真，而不是为了提高线性分辨率而被屏蔽。磁屏蔽不会显着影响双MR磁头的线性分辨率，并且可以在由待分辨的磁信号的特征位长度以外的因素限制的宽范围的间隔距离处与双MR磁头间隔开。在一个实施例中，用于双MR头的至少一个屏蔽元件可以是感应记录头的极或其他部件中的一个，并且两个头一起可以形成集成薄膜感应记录/ MR再现头组件。

摘要： A magnetic head for floppy discs has a shielding member (31, 41, 52, 71, 52A) surrounding a core (13, 53) and coil (16, 54) of the head so as to prevent the head from being adversely affected by an external magnetic field. The shielding member is a stack of sheets (32₋₁ through 32₋₆, 42₋₁ through 42₋₆, 60₋₁ through 60₋₆, 60A₋₁ through 60A₋₆) and each sheet is made of magnetic metal such as permalloy and is fixed on a gimbal plate (17, 17A) together with the magnetic head. Insulator layers (43, 72) made of thermoplastic resin may be provided between sheets of the stack of sheets to adhere the metal sheets to one another and to electrically insulate the metal sheets from one another.
