摘要： Provided is a magnetic head having a magnetic thin film structure that reduces the effect of a stray field and generates a magnetization reversal at a high speed. The magnetic head includes a first pole, a second pole spaced apart from the first pole, and an induction coil that induces a magnetic field in the first and second poles, wherein the first and second poles include a pole tip in which a leakage flux for recording is generated, and a head yoke that guides the flux flowing in the poles, and at least one implant for controlling a magnetic domain, the implant formed in at least one of the first and second poles. The magnetic thin film can effectively reduce the effect of a stray field entering from the outside, and can control a domain wall motion so that high speed magnetic recording is possible, by generating a magnetization reversal at a high speed corresponding to a magnetic field applied by an induction coil.

摘要： Provided is a magnetic recording apparatus including a magnetic recording medium having a magnetic recording position patterned of a magnetic substance and a read head reading information from the magnetic recording medium, wherein the magnetic recording medium includes: a data area having the magnetic recording position patterned including a plurality of data tracks; and a servo area including a servo burst for tracking the data tracks, wherein the servo burst includes a plurality of bursts deviating from one another in a downtrack direction, and a width of each of the bursts is equal to or greater than a width of the read head and narrower than twice the width of the read head. According to this structure, although data is reproduced using a read head having a greater width than a width of each of data tracks, a linear section in which an output voltage is reduced depending on a size of an off-track is formed. As a result, a dead zone can be removed.

摘要： An apparatus prevents developer wraparound in a wet electrophotographic printer using wraparound preventing units. Each of the wraparound preventing units has varied diameter parts formed at both ends of a developing roller, and matching parts formed at both ends of a metering roller to correspond to the varied diameter parts of the developing roller. Since the varied diameter parts and the matching parts are respectively installed at both ends of the developing roller and the metering roller, developer wraparound is not generated in the developing roller and a photosensitive roller during development.

摘要： An apparatus for uniformly supplying the liquid developer and an image forming apparatus having the same are provided. The developer supplying apparatus includes a manifold connected to a connection tube for supplying a liquid developer from an outside and having a developer inlet through which the liquid developer flows into a developing chamber, and a developer dispersion unit, disposed in the developing chamber and located adjacent to an upper part of the developer inlet, for guiding the liquid developer flowing into the developing chamber through the developer inlet so that the liquid developer is dispersed in a horizontal direction. The liquid developer flowing into the lower part of the developing chamber does not directly move toward the upper part of the developing chamber, but is dispersed in a horizontal direction, so that the liquid developer is uniformly dispersed into the whole part of the developing chamber.

摘要： A liquid image developing system, including a cartridge in which a developer is stored; a supply line; a development container to which the developer is supplied from the cartridge through the supply line; a photosensitive body in the development container; a development roller partially soaked in the developer in the development container and rotating opposite to the photosensitive body; a depositing member to create a potential difference required to attach the developer to a circumference of the development roller, opposite to the development roller; a metering blade to scratch the developer attached to the circumference of the development roller to a predetermined thickness; and an agitator to agitate the developer contained in the development container. Accordingly, a high-concentration developer can be directly used in the development operation without a dilution operation, and thus the structure to supply the developer can be considerably simplified.

摘要： A liquid image forming apparatus. A developing unit of the liquid image forming apparatus includes a developing container in which a developer is received, a developing roller having a portion which is dipped in the developer of the developing container, which is installed to be opposite to a photosensitive body, a cleaning roller which cleans the developer remaining on the surface of the developing roller after an electrostatic latent image is developed, and a squeeze roller which squeezes the cleaning roller before the developing roller is cleaned, and passes the air passing through the cleaning roller to the outside. The air passing through the cleaning roller does not pass into the developer and thus bubbles are not generated in the developer, thereby solving a problem of non-uniform developer attachment.
