摘要： The invention relates to magnetic recording media comprising a non-magnetic base and, applied thereto, a firmly adhering magnetic coating based on a finely divided magnetic pigment dispersed in a binder which contains at least 50 percent by weight of a special polyurethane elastomer.This polyurethane elastomer is a thermoplastic polyurethane which is soluble in tetrahydrofuran and free from isocyanate groups, and which has been manufactured from (A) 1 mole of one or more hydroxyl-containing polyesters and/or hydroxyl-containing polyethers of molecular weight from 600 to 4,000, (B) from 3.5 to 15 moles of a branched-chain aliphatic diol of 4 to 10 carbon atoms or a mixture of aliphatic diols of 2 to 10 carbon atoms, of which at least 50 mole percent is a branched-chain aliphatic diol of 4 to 10 carbon atoms, (C) from 0 to 1 mole, but not more than 15 mole percent of the aliphatic diols according to B, of an aliphatic polyol with from 3 to 6 OH groups and 3 to 18 carbon atoms, and (D) from 4.5 to 18 moles of a diisocyanate of 6 to 30 carbon atoms, the amount of NCO groups being approximately equivalent to the amount of OH groups of the sum of the components A to C.Magnetic recording media which contain such a polyurethane in the magnetic coating are distinguished by high surface hardness coupled with a markedly improved orientation ratio, a higher packing density and more uniform dispersion of the magnetic particles in the coating.

摘要： A drive apparatus for a magnetic disc, particularly a flexible magnetic disc in an envelope, distinguished by a compact design which is achieved by so designing and arranging the linkage between the drive's closure member and disc clamping member that they take up as little room as possible. By designing the linkage in the form of a roller and lever arrangement and arranging them substantially on the central longitudinal axis of the housing of the drive apparatus in the upper portion of the housing, the maximum amount of space is available on either side of the linking means for printed circuit boards and electronic components. In a very advantageous embodiment, the closure member, linkage and clamping member and part of the housing are assembled as a single unit which is ready for fitting.The drive apparatus of the invention can be used for any kind of flexible or rigid magnetic disc.

摘要： The invention concerns a system for recording and/or reproducing data signals on a magnetic recording medium, more particularly a new improved transducer locating system. The magnetic transducer is provided with an air gap for the data track and a second air gap for the reference track which latter is formed on a recording medium as a transition line between regions of varying magnetization and arranged within, or laterally of, the data track. As the transducer deviates from its desired track position, a correction signal is produced which is fed to a locating device to which the transducer is fitted, in order to adjust the position of the transducer.

摘要： A positioning device for a write/read magnetic head in a magnetic disc data storage device comprising a motor-driven guide disc, with a spiral-shaped guide wall arranged at right angles to the plane of the guide disc, for a guide element in the form of a ball-bearing on a magnetic-head support. Due to the greatly reduced friction it is possible to achieve highly accurate positioning within an extremely brief period of time and with an extremely low power requirement. This device may be used to position the heads in magnetic disc systems for the recording and/or reproduction of analog or digital signals.

摘要： The invention relates to a process for the manufacture of improved magnetic discs by applying a thin layer of a liquid dispersion of magnetic pigments and optionally further, non-magnetic, pigments in a binder mixture to a non-magnetic rigid base, and curing the magnetic coating which has been applied. The binder used is a mixture of polycondensates comprising 60 to 70% by weight of a solid curable polycondensate of 2,2-bis(4-hydroxyphenyl)-propane and epichlorohydrin having an epoxy equivalent weight from about 400 to 2,500 and a melting point from about 50.degree. to 150.degree. C, 10 to 30% by weight of a curable allyloxybenzene-formaldehyde condensate of the resol type with free methylol groups or with methylol groups etherified with a lower alcohol, and having a molecular weight of less than 1,000, and 10 to 30% by weight of a curable melamine-formaldehyde condensate with more than two methylol groups etherified with n-butanol or iso-butanol, and having a molecular weight of less than 2,500. A magnetic dispersion using such a binder allows the application of a firmly adhering magnetic coating, even in thicknesses of less than 4 .mu., to aluminum discs or pre-coated aluminum discs, and the magnetic coating produced has high resistance to mechanical wear.

摘要： A magnetic tape cassette comprises a housing open on one side and, movable therein, a sheath enclosing a magnetic tape roll. Detachable retaining means in the cassette hold the sheath and the roll in position while the cassette is not on the recorder. The retaining means are detachable by unlatching means when the cassette is fitted to the recorder, so that, following a movement of the sheath, the cassette is opened to allow the roll to emerge at least partially from the cassette and the circumference of the roll to be rotated by means of a recorder-associated capstan provided outside the cassette. Further advantageous embodiments of the invention concern the cassette and the recorder. The cassette of the invention and the recorder associated therewith can be employed in all fields of magnetic tape recording and reproduction. Its application to a magnetic tape system with a self-threading tape end entails advantages.
