摘要： Method of configuring digital information in a recording storage media so as to significantly increase the information storage capacity of the media and the media containing such configured digital information. Information containing markers (P) are arranged and configured along tracks (N) in the media in a manner such that markers of adjacent tracks are offset relative to one another. Inter-track spacings (S2) of arcuately shaped tracks on a storage media are progressively reduced as a function of the radial spacing of the tracks from their center of curvature, further increasing the marker packing density. Return to zero pulsed modulation schemes are employed to maximize the amount of information recorded in a given number of marker locations. Drive means for reading digital information configured on storage media according to the principles of this invention are provided.

摘要： A magnetoresistive sensor (10) includes groups of MR elements (R1-R6) arranged on a non-magnetic substrate for selective connection to detect and sense magnetic information recorded on a number of different diameter encoder wheels (12) of which each diameter wheel may have a different number of pieces of magnetic information recorded at corresponding different wavelengths (τ ) on a circumferentially running track (20) located on the circumferential face (18) of the wheel. The MR sensor (10) includes an additional MR element arrangement (R7, R8) for detecting and sensing index magnetic information recorded on an additional circumferentially running track (22) located on the circumferential face (18) of the wheel (12). The connection arrangement of the MR elements is such to form external power supply connection terminals (50, 54) which have a width substantially larger than the width of the MR elements and surround the MR elements covering a substantial portion of the substrate surface to form a heat sink to eliminate thermal gradients from developing across the substrate thereby providing thermal stability.

摘要： For effecting high density magnetic recordings on a mag netic record member (50) coated with magnetic recording ma terial, a plurality of different recordings may be provided as overlapping domains along a single select magnetic record track, thus multiplying the total amount of information which may be recorded along each record track of multiple track re cord member (50). A magnetic transducer (17) mounted on a support (35) is pivotally driven to variably align its pole pieces and recording or reproduction gaps with a select record track of a record member (50) to provide respective recordings, the domains of each of which are differently aligned from the do mains of the others, permitting such different recording to overlap along the same length of the same track and to be dis cretely detected by suitably aligned pickups.

摘要： On décrit un procédé amélioré de configuration d'informations numériques dans des supports d'enregistrement de stockage, permettant d'accroître de manière significative la capacité de stockage d'informations des supports ainsi que les supports contenant les informations numériques ainsi configurées. Des marqueurs (P) contenant des informations sont arrangés et configurés le long de pistes (N) sur les supports de sorte que les marqueurs de pistes adjacentes sont décalés les uns par rapport aux autres. Des écartements interpistes (S2) de pistes arquées sur un support d'enregistrement sont réduits progressivement en fonction de l'écartement radial des pistes depuis leurs centres de courbure, en accroîssant ainsi la densité de tassement des marqueurs. Des processus de modulation par impulsions à retour à zéro sont utilisés pour porter au maximum la quantité d'informations enregistrées dans un nombre donné d'emplacements de marqueurs. Sont également décrits des lecteurs permettant la lecture des informations numériques configurées sur les supports de stockage conformément aux principes de la présente invention.
