摘要： A magnetic head comprises a pair of core pieces with a spacer interposed therebetween which defines a gap, a yoke which interconnects the ends of the both core pieces located remote from the gap, a bobbin into which the both core pieces and the yoke are fitted to maintain them joined together, and a coil wound around the bobbin. The head is manufactured by the steps of joining together a pair of core pieces with an interposed spacer which defines a gap, applying an adhesive to the mating ends of the both core pieces and the yoke, and fitting the core pieces and the yoke into the bobbin.

摘要： A magnetic erasing head for magnetic recording apparatus using a static magnetic field. The erasing head includes at least three magnetic poles all of which are arranged to scan the same recorded track on the tape. The first and third poles have the same polarity while the second pole has opposite magnetic polarity. The first pole is arranged to engage the full width of the track and magnetizes it with one polarity. The second pole faces the upper half of the track and magnetizes it with the opposite polarity. The third pole engages the lower half of the track and magnetizes it with the same polarity as the first pole. After passing by these three poles, substantially one-half of the recording track is magnetized with one polarity and the other half of the track is magnetized with the other polarity so that distortion of output signals is maintained small or eliminated for various magnetic tapes having different coercive force values.
摘要翻译：一种使用静磁场的磁记录装置的磁性擦除头。擦除头包括至少三个磁极，其全部被布置成扫描磁带上相同的记录磁道。第一和第三极具有相同的极性，而第二极具有相反的磁极性。第一极被布置成接合轨道的整个宽度并且以一个极性使其磁化。第二个磁极面对轨道的上半部分，并以相反的极性对其进行磁化。第三极接合轨道的下半部，并以与第一极相同的极性对其进行磁化。在通过这三极之后，基本上一半的记录磁道被磁化为一个极性，磁道的另一半以另一个极性被磁化，使得对于具有不同的各种磁带的输出信号的失真保持较小或消除强制力值。

摘要： A device for recording and playing back information in a spiral-like track or a track consisting of concentric circles present on a disk-shaped recording medium, in which the storage and playback element consists of a sheet of magnetizable material which contains a single-wall magnetic domain. The polarity of a radially directed magnetic field can be inverted according to a frequency modulated with a signal to be recorded so as to record information together with the stray field of the domain. A detector is present to detect position variations of the domain upon playing back and means are present to correct the position of the domain in the sheet by way of fine control upon playing back.

摘要： A handheld device for recording magnetic cueing and starting signal information on a magnetizable surface such as used on motion-picture film. A recording head is passed over the film and across the gap head an alternating mmf. is generated by a rotated magnet or an electromagnetic coil synchronized to the movement of the gap.

摘要： An elongated flat strip of insulative material having at one end a central portion, lateral portions disposed on either side of the central portion, and transverse portions joining the lateral portions to the central portion. The central portion protrudes further than the lateral portions. Wire-connecting pads are concentrated in a line across the central portion and the lateral portions. Conductors are arranged along the length of the strip. The ends of the conductors terminate respectively at the different pads. The conductors terminating at the pads on the lateral portions are mounted along the outer edges of the strip and the conductors terminating at the pads on the central portion are arranged along the center of the strip. As a result, the conductors lead to each portion without passing the pads on the other portions. Each transverse portion has a double-reverse bend that places the pads on the lateral portions in a row stepped back from and beside the row of pads on the central portion. The end of the strip lies in a recess in a magnetic head assembly. The head windings are directly connected to the pads.
