摘要： A plurality of read/write heads is disclosed for a magnetic media storage system, such as, for example a magnetic tape drive. Each head can include a plurality of data channels. In addition to enhancing data throughput, the plurality of read/write heads can be aligned to read or write bands of tracks on a magnetic tape with only one positioning mode (e.g., without coarse position actuation and control), and also obtain optimum yield and crosstalk values.

摘要： A lapping sensor is provided for measuring a throat height of a thin film recording element during a mechanical lapping process. The recording element is fabricated in a photolithographic process and has a zero throat location. The lapping sensor includes a sensor device for generating an output signal indicative of the throat height during the lapping process, and a calibration switch in electrical communication with the sensor device. The switch is fabricated during the same photolithographic process as the recording element and generates an output signal during the lapping process indicative of a low resistance value up to a selected distance from the zero throat location of the recording element, and indicative of a high resistance value thereafter. Transition of the switch output signal from the low resistance value to the high resistance value during the lapping process is used to calibrate the sensor device output signal to the selected distance from the zero throat location of the recording element. A method for manufacturing the lapping sensor is also provided.

摘要： This method of manufacturing a multi-turn multi-track composite recording head increases the cross sectional area of the conductors used to implement the windings in the recording head. This is accomplished by etching a recess into the ferrite substrate of the first ferrite magnetic pole piece to receive the winding. This recess may be deep enough to incorporate the entirety of the winding. This configuration does not constrain the gap size but simply increases the space into which the winding is placed. The thickness of the winding deposited in this space is no longer constrained by the dimensions of the gap but can be equal to the gap dimension plus the depth of the recess etched into the ferrite substrate.
摘要翻译：制造多回转多轨复合记录头的这种方法增加了用于在记录头中实现绕组的导体的横截面积。这通过将凹入部分蚀刻到第一铁氧体磁极片的铁氧体衬底中以接收绕组来实现。这个凹槽可能足够深以结合整个绕组。该配置不限制间隙尺寸，而是简单地增加绕组放置到其中的空间。沉积在该空间中的绕组的厚度不再受到间隙的尺寸的限制，而可以等于间隙尺寸加上蚀刻到铁氧体衬底中的凹槽的深度。

摘要： A servo write head for magnetic tape is provided. The invention includes first and second non-magnetic substrates and first and second magnetic layers deposited between the non-magnetic substrates. A middle non-magnetic substrate is then deposited between the first and second magnetic layers and forms the magnetic gap.
