    Abstract: It is proposed to make thin film magnetic field sensors with perpendicular axis sensitivity, based on a giant magnetoresistance material or a spin tunnel junction, by making use of ferromagnetic layers that have strongly different uniaxial anisotropies and/or have a modified magnetization curve by antiferromagnetic exchange coupling with an auxiliary ferromagnetic layer. A strongly miniaturizable magnetic field sensor is based on four spin tunnel junctions, together forming a Wheatstone bridge. The magnetically sensitive electrode functions as well as a laminated flux concentrator, resulting in a low noise single domain configuration. The very simple design also allows easy definition of the fixed magnetization direction of the counter electrode. Very high output voltage combined with very low power.

    Abstract: The invention concerns a data medium optical recording/reading device, comprising: a transparent substrate (2) with a substantially planar surface (20) bearing at least a couple of electrodes (E1-E2) defining an air gap zone (3) whereof the dimension substantially corresponds to the dimension of the data to be recorded or read. A couple of electrodes (E1-E2 or E3-E4) constitutes an incident magnetic wave resonator with a component of its electric field parallel to the alignment direction of the electrodes; an optical source (1) illuminates said electrodes by means of an optical beam (F1) whereof one component of the electric field is parallel to the alignment direction of the couple of electrodes. In such conditions, when excited by the beam F1, the electrodes re-transmit a beam concentrated at the air gap (3). said re-transmitted beam enables to record/read a data medium set in the proximity of the electrodes.

    Abstract: A dual tape drive system is described for accepting either a digital data tape cartridge (13) for data backup or a standard audio cassette tape (15) for audio play and record. A single dual purpose tape head may be utilized for interfacing with both digital data tape cartridges and audio cassette tapes. In an alternative embodiment of the dual tape drive system, separate tape heads (26, 28) may be utilized such that an "audio" head (28) is dedicated to cassette tapes (15) while a "data" head (26) is dedicated to digital tape cartridges (13). The dual tape drive system may exist as a stand alone device or may be integrated into a computer system whereby the tape drive is controlled through a keyboard operatively coupled to the computer system.

    Abstract: A conventional video recorder has a top plate (2) mounting a tape supply spool (22) and tape take-up spool (22a) upon a common shaft (19). A recording assembly (6) has a conventional video recording drum and combines with a master cassette holder (4) to complete a cassette recording station. A roller system guides the tape from the supply spool (22) through the recording station to the take-up spool (22a). Stepper motors (3) provide rim drive to the spools (22) and (22a) and vacuum troughs (8 and 9) and associated photoelectric devices provide for speed control of the tape transport functions as a whole to ensure that tape is conveyed at a uniform speed without slack.

    Abstract: Disclosed herein are embodiments of a heat-assisted magnetic recording (HAMR) head that includes a near-field transducer (NFT) with a trailing bevel. Also disclosed are sliders and data storage devices comprising those HAMR heads, and methods of manufacturing HAMR heads with NFTs having trailing bevels. A HAMR head comprises a waveguide core, a main pole, and a NFT comprising a trailing beveled edge at an acute angle to an air-bearing surface (ABS) of the HAMR head. A method of fabricating a HAMR head comprises depositing material for a NFT, creating a trailing-side surface of the NFT, and creating a trailing beveled edge in the trailing-side surface of the NFT at the ABS, and forming a dielectric layer over the trailing beveled edge. The trailing beveled edge is at an acute angle to the ABS, and a remainder of the trailing-side surface of the NFT is substantially perpendicular to the ABS.

    Abstract: A suspension is described. The suspension includes a base plate and a load beam coupled to the base plate. The base plate includes a distal elongated element and a proximal elongated element. The distal elongated element includes at least one non-straight baseplate edge and the proximal elongated element includes at least one non-straight baseplate edge. The load beam includes a first mounting shelf and a second mounting shelf. The load beam is coupled to the base plate such that the first mounting shelf is exposed adjacent to the distal elongated element, and the second mounting shelf is exposed adjacent to the proximal elongated element. The first and second mounting shelves are configured to receive an actuator, such that an edge of the actuator and the at least one non-straight baseplate edge forms a gap.
