摘要： A magnetic head having an enhanced recession resistance characteristic, and a method of fabricating the magnetic head having the enhanced recession resistance characteristic is disclosed. The improvement is the addition of one or more hard protective layers exposed edgewise at the media-head interface. Each protective layer is formed between the substrate and the top closure of the magnetic head to a thickness of greater than approximately 0.2 micrometers and a hardness of greater than approximately 850 Knoop. The protective layers are formed by depositing a hard metal film above, below or within the read and write transducers inside the magnetic head. The hard metal film is selected for its hardness, ease of use during the fabrication process, and compatibility with adjoining materials. The hard metals include, but are not limited to, chromium, iridium, rhodium, tantalum, titanium and tungsten.

摘要： A magnetic head having a pair of longitudinal channels in a tape bearing surface that flank each transducer. The channels reduce the effective height of debris in the channels near the transducers. The channel floors may have a transverse slope, and the tape bearing surface between channels may be tapered. Transverse slots help direct debris away from the transducers. The channels overlap the end sections of the transducers and help to define the shape and position of the transducer's active section. When applied to a two pole write transducers, the channels narrow and equalize the effective width of the top and bottom poles. Narrow equal-sized poles can write narrow data tracks with a track width that is independent of the magnetic medium's direction of motion.

摘要： The present invention decreases the number of repositions during read back by making use of multiple read elements associated with each data track. A tape system includes a tape head with two read elements associated with each data track to be simultaneously read. Each read element generates a read signal in response to information recorded on the data track. Read electronics convert the read signal into read data. Control logic selects one of the two read elements as a source for output data for each data track. In response to a read error, output data is obtained from the other of the two read elements.

摘要： A method of fabrication and a magnetic transducer having an inverted write element with a zero delta in pole tip width to provide improved bi-directional control over write track width and written erase bands on media. The transducer includes a top pole and a bottom pole configured to provide the same write track width and relatively small erase bands when either pole is the trailing pole depending on direction of movement of the media relative to the transducer. The bottom pole has an upper portion and a lower portion. The bottom pole upper portion width is less than the bottom pole lower portion width. The top pole has a main portion formed opposite to the bottom pole upper portion. The top pole main portion has a main portion width which is equal to the bottom pole upper portion width.

摘要： The present invention decreases the number of repositions during read back by making use of multiple read elements associated with each data track. Each of a plurality of sets of read electronics receives the read signal from either one or the other of the two read elements associated with each data track and converts the received read signal into read data. For each data track, control logic selects one of the two read elements as a source for output data. In response to a determination that a read error has occurred, the control logic selects the other of the two read elements as the source for output data. For each data track, one read element is offset relative to the other read element in an offset direction normal to the tape direction.
