摘要： A preferred embodiment of an electromagnetically controlled scanning magnetic transducer is described having two confronting core poles defining a physical transducing gap therebetween. A control winding is associated with each core pole. A control current applied to each control winding selectively saturates a portion of each core pole facing a record medium. Each saturated face portion defines an adjacent unsaturated highly permeable face portion. The highly permeable face portions of each core pole overlap across the gap to define a transducing zone. The information signal and control windings are arranged relative to one another to obtain information signal and control flux paths extending perpendicular to one another.

摘要： In a recorder/reproducer apparatus, a scanning magnetic transducer for the magnetic recording and reproducing of a data signal in a magnetic storage medium. The transducer includes one or more elongate main pole segments embedded in the periphery of a rotary drum and oriented at an angle relative to the drum's axis of rotation. An elongate stationary pole with an electromagnetic winding coupled to the data signal is spaced from the drum and oriented generally parallel to the axis of rotation. A magnetic tape is transported between the two poles in contact with the main pole segments on the drum and spaced from the stationary pole. Rotation of the drum during recording and/or playback causes the area of intersection, that is, the opposed common area or confronting face portions, of the stationary pole and each of the successive main pole segments to be moved or scanned along the face of the stationary pole. A concentrated magnetic field corresponding to the data signal is generated at the area of intersection and thus also is moved along the length of the stationary pole. As a result, a series of generally transverse tracks of magnetic states are recorded in, or reproduced from, the tape as it is moved between the main pole segments and the stationary pole. Plural stationary poles may be used to provide a multiple track magnetic transducer for recording and reproducing multiple tracks in the magnetic storage medium.

摘要： A magnetic transducer for reproducing/recording high frequency signals with a magnetic tape medium includes a pair of opposed transducer head halves separated by an insulation gap and bonded together to form a Y-shaped pole structure, each half including a laminated at least partially ferromagnetic core portion bounded on opposite surfaces with conductive layers, each of which forms a winding coil portion. Each core section is formed as one-half of a Y-shaped cross-sectional configuration having a leg portion and an angularly disposed arm portion, the distal end of which is capped with a block-shaped ferromagnetic pole tip in magnetic path relation therewith, the two pole tips lying in a common plane transverse to the plane of the gap. The conductive layers on the outer and inner surfaces of the laminated core section form outer and inner conductors which, when conductively interconnected, such as by jumpers, are configured to form a one or two turn coil for the transducer. The inner conductor is of an inverted generally U-shaped configuration with the bight portion of the two inner conductors passing through, and substantially filling, the openings of the Y-shape on opposite sides of the insulation gap layer beneath the pole pieces.The method of fabricating the magnetic transducer generally comprises the steps of forming at least two generally identical transducer head halves, each having generally one half of a Y-shape, commencing with providing a substrate having a surface shaped to define the core configuration and having a band shaped to define the pole configurations; applying a conductive layer to the surface for providing an outer coil conductor; alternately applying laminae of insulating and magnetic material to form a laminated core section; applying a conductive layer over an insulation layer about the face and side edges of the laminated core section for providing an inner generally U-shaped coil conductor; forming, in the band, a pole piece of magnetic material at the distal end of the arm of the core section; bonding two such transducer head halves in facing relation to from a Y-shaped transducer with the bonding material being insulating and forming the gap between the two pole pieces.

摘要： Magnetic record media are described that have an overlying or underlying magnetically saturable high permeability keeper layer in addition to a high coervicity magnetic layer in which magnetic signals are stored. These media are used in magnetic signal processing devices whose transducers are capable of generating a keeper layer-saturating bias flux. In signal reproduction the bias flux magnetically forms a saturation zone in the nature of virtual gap in the keeper layer that directs signal flux between the media and the transducer.

摘要： A magnetic shield is provided for stray flux reduction from a transducer into a laterally disposed adjacent transducer. The shield substantially covers the transducing winding and extends in close proximity over a rear portion of the magnetic core. The shield does not extend over the transducing gap, to prevent magnetic coupling therewith. In the preferred embodiment a staggered two channel video type transducer has shields on opposite sides thereof in direct contact with the cores. The shields have recesses to accommodate the windings.

摘要： A magnetic storage system includes a magnetic storage medium comprising a keeper layer of relatively low permeability soft magnetic material deposited upon a magnetic storage layer or between multiple magnetic storage layers. The low permeability keeper layer may be disposed either above or below the magnetic storage layer. In the unsaturated state, the keeper layer acts as a shunt path for flux emanating from recorded transitions on the magnetic storage layer, producing an image field of the recorded transitions in the keeper. This shunt path prevents signal flux emanating from the recorded transitions from reaching the head. To read data from a recorded transition on the magnetic storage layer, a bias current is applied to windings of the head, creating a bias flux which saturates a portion of the keeper layer. Once saturated, this portion of the keeper can no longer shunt flux emanating from the recorded transition, which is the region represented by the head reproduce transducer.
摘要翻译：磁存储系统包括磁存储介质，磁存储介质包括沉积在磁存储层上或多个磁存储层之间的相对低磁导率软磁材料的保持层。低渗透性保持层可以设置在磁性存储层的上方或下方。在不饱和状态下，保持层用作从存储层上的记录跃迁发出的磁通的分流路径，从而产生保持器中记录的转变的图像场。该分流路径防止从记录的转变发出的信号通量到达头部。为了从磁存储层上记录的转换中读取数据，偏置电流施加到磁头的绕组，产生使保持层的一部分饱和的偏置磁通。一旦饱和，保持器的该部分不再能够分离从由磁头再现传感器表示的区域的记录转变发出的磁通。
