Abstract: 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.

Abstract: Apparatus and methods for reducing the sensitivity of spin valve sensor read heads for magnetic tape applications are provided. The apparatus and methods compromise the large output gain derived from using state of the art spin valve sensors in order to reduce the flux capture and thus, the signal distortion in the spin valve sensor. In order to provide a reduced sensitivity spin valve sensor, one or more of the basic sensitivity of the spin valve, the flux carrying capability of the free layer, and the flux injection efficiency of the spin valve head structure are modified to reduce the flux capture by the sensing layer.

Abstract: Magnetic tape onto which information may be recorded on either side exhibits the risk of having information recorded on one side affect the opposite side when the two sides are adjacent, such as when the tape is wound in a tape pack. The chance that information recorded onto one surface of a double sided magnetic tape will affect information recorded on the other surface of the magnetic tape is reduced by keeping fields emanating from a recorded region less than about one-half the coercivity of the magnetic medium onto which the information is recorded.

Abstract: A thin film write head allowing substantially the same amplitude of input current to be used for writing both data transitions and equalization pulses onto a magnetic tape is described. Data transitions occur at a frequency no greater than a data frequency. Each equalization pulse is a signal written at an equalization frequency much greater than the data frequency. The thin film write head includes a top pole (54), a bottom pole (52), and a conductive coil (56), between the top and bottom poles. The top pole (54), bottom pole (52), and conductive coil (56), form an electromagnet for writing the write-equalized digital data stream onto the magnetic tape by converting an input current through the conductive coil into a head field. Conversion of the input current at the data frequency results in substantially the same head field amplitude as conversion of the input current at the equalization frequency. This may be achieved by increasing the gap depth (104) to cause saturation at the data frequency.

The assembly includes an interior tape head module (14) having a magnetic gap (18) with 16 or more tape head elements, and a first exterior tape head module (12) adjacent one side of the interior module. The first exterior module has a magnetic gap with 16 or more tape head elements. The assembly also includes a second exterior tape head module (16) adjacent the other side of the interior module. The second exterior module has a magnetic gap with 16 or more recording elements. The distances between consecutive magnetic gaps of the interior and exterior modules are each approximately 60 microns, and the interior and exterior modules together define a semi-circular tape interface contour. In the preferred embodiment, the interior module is a write head with 16 write elements, and the exterior modules are each read heads with 16 data read elements and 6 servo read elements.
