摘要： It is the objective of the present invention to provide a method to readout magnetic storage media that provides a high throughput for magnetic tapes and readouts the magnetic information with a high fidelity.
This objective is achieved according to the present invention by a method for contactless readout of the magnetic information stored on magnetic tapes (4), said magnetic information being encoded by the magnetization value and direction stored on the magnetic tapes (4), comprising the steps of:
a) providing a first circularly polarized x-ray beam (c+) and a second circularly polarized x-ray beam (c-);
b) orienting the first circularly polarized X-ray beam (c+) and the second circularly polarized X-ray beam (c-) towards the magnetic tape (4);
c) reading out the first circularly polarized X-ray beam (c+) and the second circularly polarized X-ray beam (c-) after their passage through the magnetic tape while advancing the magnetic tape, and
d) determining the magnetic information by the difference between the two readout signals from the first x-ray beam (c+) and the second x-ray beam (c-) based on X-ray magnetic circular dichroism.
Based on this beam splitting scheme, a real-time readout of the magnetic signal stored on the magnetic tape can be achieved by the evaluation of the intensity signals for the c+-X-ray beam and the c- X-ray beam.

摘要： A tape drive that passes first and second sides of a storage tape by respective first and second tape head assemblies disposed on a common side of a tape path of the tape to allow for dual-sided recording and/or reading of the tape by the tape head assemblies. Tape leaving a cartridge/supply reel within the tape drive may be wound over one or more tape path guides (e.g., rollers) to face a first side of the tape (e.g., with a first magnetic layer) towards a first tape head assembly. The tape may subsequently be wound over one or more additional guides and then passed in front of a second tape head assembly such that the opposing side of the tape (e.g., with a second magnetic layer) faces the second tape head assembly. After passing by the second tape head assembly, the tape may be wrapped onto a take-up reel.

摘要： The present invention provides a card reader that can meet the customer needs to a certain extent even when a non-standardized transparent card is inserted, while considering a background of card design that spreads in a wide variety these years. Concretely to describe, the card reader includes: a card path (2) through which a card having a magnetic stripe is transferred; a magnetic head (10) placed in the card path (2); and card position detecting sensors (a photo sensor (8a) and others) for detecting a position of the card. Meanwhile, the card position detecting sensors (the photo sensor (8a) and others) are located at positions where the magnetic stripe passes through in the card path (2).

摘要： Embodiments of the present invention are directed to the design and implementation of backward-compatible magnetic tape drives (102) that are read/write compatible with a current magnetic-tape format (1820) as well as one or more previous magnetic-tape formats (1802 and 1804). Embodiments of the present invention include read/write tape-head configurations (1902, 1904, 1906, 1908-1923, 1930, 1932, 1934, 2102) and corresponding magnetic-tape-drive-component features (518) that allow a magnetic-tape drive to read and write magnetic tapes formatted according to different formats.

摘要： Writing data to magnetic tape is performed by receiving data from a host, establishing sub data sets, computing C1 and C2 ECC, forming Codeword Quad sets, writing a beginning Data Set Separator to a magnetic tape, writing a plurality of contiguous instances of the CQ Set to the magnetic tape and writing a closing DSS. The number of instances of each Codeword Pair is increased, thereby allowing the benefits of writing short tape records and improving reading reliability while reducing susceptibility to mis-tracking errors and large defects, and while reducing the negative impact on data reliability. Otherwise unused latency times are utilizing and therefore no performance penalty is incurred.

摘要： The present invention relates to a magnetically recorded data reproduction apparatus which reproduces magnetically recorded data using a magnetoresistive head and method thereof. In this invention the recorded data are reproduced by a magnetoresistive head 2 and supplied to a reproduction amplifier 4. The signal from the reproduction amplifier 4 is then supplied to a high-pass filter 5 and a frequency component of, for example, 1 MHz or lower, is cut off. The signal from the HPF 5 is supplied to an integrating equalizer 6, a phase equalizer 7 and an analog cosine equalizer 8. The signal from the equalizer 8 is supplied to an AGC amplifier 10 through a low-frequency component correction circuit 9. The signal from the AGC amplifier 10 is supplied to an A/D converter 11. Further, the signal from the AGC amplifier 10 is supplied to the digital PLL circuit 12 and the extracted clock signal is supplied to the A/D converter 11. The digitized signal is then supplied to, for example, a Viterbi decoder 13 and the decoded signal is obtained at an output terminal 14. Thus, the effect of noise due to the so-called thermal asperity (TA noise) is removed, thereby preventing increases in the error rate of the reproduction signals due to the effect of TA noise and the occurrence of problems in equipment.

摘要： A method of protecting data on a recording medium against an adjacent track erase (ATE) effect, and a recording medium having a program therefor are provided. The method includes accumulating a number of turns of write operations in respective sub-areas, wherein the recording medium is divided into a plurality of sub-areas; and rewriting data on a sub-area of which an accumulated number of turns of write operations is greater than a limited number of turns of write operations. Accordingly, before data written on an adjacent track can be damaged by the ATE effect, data is rewritten and safely preserved.

摘要： A digital magnetic recorder having a recording compatibility with respect to formats similar to each other in the basic parts. Conventionally, an MP tape (metal-coated tape) is used for the DVCPRO format; and an ME tape (metal-evaporation tape) is used for the DV format. When a format recognizing section (800) outputs a format recognizing signal Sf (dvcpro), equalizing characteristic selecting sections (27, 28) select recording amplifiers (22p, 25p) adapted to the DVCPRO format to select recording equalizers (21p, 24p) adapted to the DVCPRO format. When the format recognizing section (800) outputs a format recognizing signal Sf(dv), the equalizing characteristic selecting sections (27, 28) select recording amplifiers (822d, 825d) adapted to the DV format to select recording equalizers (821d, 824d) adapted to the DV format.
