An arcuate scan tape drive for transferring data to and from a data tape (26). Situated within a base (22) and cover (24) is a head carrier assembly (36) for recording data onto and playing back data from the data tape which advances in a longitudinal direction past the head carrier assembly. The head carrier assembly (36) includes an inside-out spin motor (40) for rotating the head carrier assembly and a pivot motor (72) at the rear of the head carrier assembly for pivoting the head carrier assembly in a plane perpendicular to the longitudinal direction of advancement of the tape (26). The spin motor (40) and pivoting motor (72) receive servo signals from a controller so as to continuously adjust the position of the core elements (46) with respect to the data tape so as to align the core elements with the arcuately-shaped data tracks (118).
摘要:
A magnetic transducer and suspension assembly suitable for use in both contact recording and in winchester-type applications is described. A generally rectangular elongated flat suspension member includes a vertical-type inductive read/write transducer formed integrally with the suspension member and is embedded in one end of the suspension member. The vertical inductive transducer is suitable for vertical recording applications. The transducer vertical magnetic pole tip and magnetic yoke structure are formed at one end of the suspension member with the vertical pole tip extending to and exposed at an air bearing surface formed on the lower surface of a slider-shaped protrusion extending from the lower surface of the end of the suspension member. The integral transducer/suspension assembly can be adapted for either flying above the recording media or for use in continuous contact with the recording media. The air bearing surface is formed on the lower surface of a wear pad. The fabrication of the transducer/suspension assembly is adapted to be performed at the wafer level.
摘要:
A magnetic head wherein a flat head (FH1) is mounted on a rotary drum (DR1) on which a magnetic tape (MT) can be wound, the flat head (FH1) has a smooth flat face (PL1) opposed to the magnetic tape (MT) and subjected to fluid interference with the magnetic tape (MT), and a head element (HE1) in contact with the magnetic tape (MT) and subjected to magnetic interference therewith is disposed in the range where the magnetic tape (MT) is in contact with the smooth flat face (PL1).
摘要:
A process is disclosed for reducing the friction between a rotating head drum and a tape-shaped recording medium which surrounds the head drum for recording and/or playing back information. In order to shorten access time to information stored on the tape-shaped recording medium, there are recorders in which the recording medium mounted in a cassette remains threaded even during rewinding and surrounds the head drum in the same way as in the play and search modes. Because the tape remains threaded during rewinding, such recorders, also called full-loading recorders, suffer from increased friction problems, which are avoided by relatively costly measures. The object of the invention is to reduce such costs caused by rewinding in a full-loading recorder. For that purpose, the speed of rotation of the head drum (1) is increased by a factor, preferably factor 2, during rewinding. The invention is particularly suitable for video recorders working according to the full loading process.
摘要:
Bei einem Scanner für ein Magnetbandgerät mit einer durch einen Kopfspalt (13) getrennten Ober- und Untertrommel (11, 12), mit einem drehbar im Kopfspalt (13) gelagerten Kopfrad (14) und mit einem schräg über den Kopfspalt (13) geführten Magnetband (16) wird der störende Einfluß von Luftfilmen unter dem Band dadurch verhindert, daß die Bandlauffläche beiderseits des Kopfspaltes (13) Vertiefungen (22, 23) aufweist, die der Dicke der bei Drehung des Kopfrades (14) unter dem Band (16) gebildeten Luftfilme (24, 25) angepaßt sind.
摘要:
Magnetic transducer assembly (1) including a plurality of magnetic cores (2a-d) affixed to a nonmagnetic slider (4), the slider having a multiplicity of fluid bearing surfaces (7a-d) for supporting the magnetic transducer assembly on a fluid bearing proximate to a rotating surface such as a magnetic disc. Each magnetic core has a corresponding slider fluid bearing surface of equal width, the magnetic cores being affixed to the trailing edge (3) of the fluid bearing surfaces. The slider provides additional fluid bearing surfaces (8a-b) intermediate the corresponding fluid bearing surfaces.
摘要:
An air bearing (20) for use on a tape transport apparatus is connectable to an air source (80) and supports a tape (14) on a cushion of air as the tape is transported. The air bearing comprises a housing (22) having an air inlet (34) adapted for connection to the air source and a bearing member (40) disposed on the housing and located so that the tape is transported across a bearing surface. The housing and the bearing member are configured to form a plenum chamber having an interior in fluid communication with the air inlet. At least a portion of the bearing member is fabricated out of a porous material allowing pressurized air in the plenum chamber to pass therethrough and out of the bearing surface to produce the cushion of air. A tape transport apparatus incorporating these features is also provided.
