    摘要： Techniques of the present invention include detecting a touchdown between a read/write head of a disk drive and a surface of a magnetic disk using multiple touchdown sensors located at an air-bearing surface (ABS). The multiple sensors increase the likelihood that a touchdown event—i.e., a portion of the ABS of the head contacting the underlying magnetic disk surface—will be detected. During touchdown, the portion of the head contacting the magnetic disk generates frictional heat which changes a characteristic (e.g., the electrical resistance) of at least one of the sensors located at the ABS. When the sensors are connected to a detection circuit, the changing characteristic may be monitored to identify a touchdown event. The touchdown sensors may be, for example, electrically connected in either series or parallel to the detection circuit. Thus, as long as the electrical resistance of one of the sensors is changed, a touchdown event may be detected.

    摘要： An apparatus for rotary cathode electroplating having a head assembly, a substrate/thief assembly having a thieving ring which includes a number of individually chargeable segments, and a secondary induction assembly including a secondary core and a secondary winding. A motor drives the substrate/thief assembly to rotate relative to the head assembly. A controller directs electrical charge to each of the individually chargeable segments of the thieving ring. An electrical storage device stores electrical energy which is to be supplied to the controller. A charging apparatus induces a magnetic flux which induces an alternating current in the secondary winding of the secondary induction assembly. A converter converts the induced alternating current to direct current, which is then stored on the electrical storage device.

    摘要： A dual gap horizontal thin film inductive head is provided which writes wide and reads narrow so as to avoid noise problems when reading an information track on a magnetic medium. The head has first and second gap layers between first and second horizontal pole tips. The pole tips and the corresponding pole pieces of the head are constructed of a high magnetic moment material, such as NiFe (Permalloy). The first gap layer is constructed of a magnetic insulator, such as tungsten, and the second gap layer is constructed of a low magnetic moment material, such as NiFeCr. Accordingly, the magnetic moment of the second gap layer is lower than the magnetic moment of the first and second pole tips and the corresponding first and second pole pieces. During recording both gap layers function as a gap because the second gap layer is saturated and behaves as a magnetic insulator. During playback only the first gap layer functions a gap because the second gap layer is not saturated causing it to behave as a magnetic conductor. Accordingly, during record the head "writes wide" and during playback the head "reads narrow." A unique method is provided for making the head which employs a vertical edge of a photoresist layer for forming the first and second gap layers.

    摘要翻译： 提供双间隙水平薄膜感应头，其写入宽且读取窄，以便在磁介质上读取信息轨道时避免噪声问题。 头部在第一和第二水平极尖之间具有第一和第二间隙层。 磁头尖端和磁头的对应极片由高磁矩材料（如NiFe（坡莫合金））构成。 第一间隙层由诸如钨的磁绝缘体构成，第二间隙层由诸如NiFeCr的低磁矩材料构成。 因此，第二间隙层的磁矩低于第一和第二极尖以及对应的第一和第二极靴的磁矩。 在记录期间，两个间隙层用作间隙，因为第二间隙层是饱和的并且表现为磁绝缘体。 在回放期间，只有第一间隙层起间隙的作用，因为第二间隙层不饱和导致其作为磁导体。 因此，在记录期间，头部“写入宽”，并且在播放期间，头部“读取狭窄”。 提供了一种独特的方法来制造采用光致抗蚀剂层的垂直边缘以形成第一和第二间隙层的头部。
