摘要： A write head for a magnetic storage system energizes a write coil for a plurality of bit intervals and selectively shutters the magnetic field to alter a magnetic domain of a magnetic storage medium for each bit interval. The position of the shutter may be controlled using a micro-electro mechanical system. Magnetic pole segments provide a loop between the write coil and the magnetic storage medium. Magnetic shielding on the shutter mechanisms controls the reflection of the magnetic fields. In a rewritable magnetic storage system, a first write coil generates a positive magnetic field and a second write coil generates a negative magnetic field. A shutter is associated with each write coil to selectively allow the positive or negative magnetic fields to alter the magnetic domain of the magnetic storage medium. The positive or negative magnetic fields can alter the magnetic domain in a collocated region of the magnetic storage medium to avoid jitter.

摘要： The magnetic head 11 is structured such that a high-density recording head core 13 and a normal recording head core 14 are assembled integrally into the same slider 12. In the same side surface of the slider 12, there are formed a first cut-out portion 15 into which the high-density recording head core 13 can be inserted, and a second cut-out portion 16 into which the normal recording head core 14 can be inserted. The two cut-out portions 15 and 16 are formed in such a manner that they respectively extend in the rotational direction (A direction) of a magnetic disc. The two kinds of head cores 13 and 14 having different recording densities are respectively inserted into and the core hold portions 18 and 19 of the cut-out portions 15 and 16 opened up in the same side surface of the slider 12, and are then fixed thereto with adhesives 24 and 25. The two head cores 13 and 14 are assembled into the cut-out portions 15 and 16 from the same direction and are then fixed to the hold portions 18 and 19 in such a manner that they are arranged in parallel to each other.

摘要： A removable device which is used during manufacturing for ESD/EOD protection and removed when the head is mounted in a drive. The device consists of crossed diodes which are mounted in the device and will connect to the readers. Each reader has two or more crossed diodes detachably coupled to its leads. The diodes are mounted on a device which is removable at the end of manufacturing assembly and the device can be reused. The device limits the voltage across a reader to the voltage limit of the number of diodes connected in series. Crossed diodes are connected in parallel with the electrical device to be protected to protect against random current spikes in either direction through the device in question. The device has leads which can be connected to an external device to measure the reader resistance or other electrical properties.

摘要： A matrix array of recording heads, wherein each head is independent from another both in terms of its magnetic circuit and excitation conductors. Each individual head has a planar magnetic circuit and an helical coil wrapped around the lower part of the magnetic circuit. The matrix array is collectively fabricated using full thin film technology on non-magnetic substrates. Preferably, the heads are aligned in an oblique lattice with the write gaps aligned along rows and offset by a constant value along columns. Each individual head is connected to the control electronics through interconnects to the backside of the wafer, allowing independent control of the write parameters. The die forming the device is shaped on its edges and top surface to optimize head/medium positioning and minimize wear.

摘要： The invention relates to data storage. The proposed method of writing data onto and reading them from a magnetic carrier (6) involves allowing a directional beam of electromagnetic radiation to act on the section (5) of the magnetic circuit (2) of the head which faces the carrier (6) to create a local reversible disturbance in the magnetic conductivity in the form of a virtual gap. The proposed head for carrying out this method comprises an electromagnetic radiation source (7) and a closed magnetic circuit (2) made of a magnetic substance with pronounced thermomagnetic properties. One section (3) of the magnetic circuit (2) has an electric winding (4) around it, while the other (5) faces the carrier (6) and is connected by means of a waveguide (7) to the electromagnetic radiation source (7).
