An improved magnetic tape guiding device for use with a magnetic tape transport system of a tape recorder and the like, and a method for using the same. The magnetic tape guiding system of the tape recorder transport system has a supply reel pole base assembly having a slant pole with a first guide unit having portions formed at both ends of the slant pole to function as a conventional roller for regulating upward and downward movement of the upper and lower edges of a moving magnetic tape, and a tension pole assembly having a tension pole with a second guide unit having portions formed at both ends of the tension pole to function as a conventional impedance roller for regulating upward and downward movement of the upper and lower edges of the moving magnetic tape. This arrangement can thus achieve 2-dimensional plane-traveling of the magnetic tape while also reducing the number of the parts of the guiding system.

A tape guide device for a magnetic recording/reproducing apparatus includes a pole base assembly to guide a tape supplied from a supply reel and passed through a predetermined path to be moved horizontally to a read surface of a head drum. The pole base assembly includes a pole base installed adjacently to or separately from one side of the head drum during a loading/unloading operation of the tape. The pole base assembly also includes a pole unit including a spiral flange inclined to the pole base to be in a horizontal direction to the read surface of the head drum, to guide the tape entering the head drum to be inclined at a predetermined angle and positioned in the horizontal direction to the read surface.

A moving deck plate for a camcorder has a sub-chassis slidably moving with respect to a main chassis. A drum base is integrally formed with the main chassis. A pair of stationary guide rails are integrally protruded from both sides of the drum base. A pair of movable guide rails provided at the sub-chassis are docked to the pair of stationary guide rails to form a moving path, along which a pair of pole bases move to draw a magnetic tape from the tape cassette. One of the stationary guide rails is coupled to the drum base by a first bridge-type reinforcing rib.

A magnetic recording and reproducing apparatus is provided which comprises a deck mounted with a drum motor and a capstan shaft, a main sliding member slidably installed on the deck and being driven by a driving force of the drum motor, a pivot lever rotatably installed on the deck and supporting a pinch roller for guiding a tape to be in contact with the capstan shaft, a review arm rotatably installed on the deck and being connected to the pivot lever by means of an elastic member, and a compressing lever for connecting the review arm and the sliding member. The compressing lever is driven by a driving force from the sliding member, and compresses the review arm in a direction such that the elastic member is stretched. The pivot lever is then rotated by the stretched elastic member and adheres the pinch roller closely to the capstan shaft.

Disclosed are a reel brake device and a magnetic recording and reproducing apparatus having the same. The reel brake device comprises a tension band mounted on an outer circumference of a reel disc to control tension, the reel disc which is rotatably mounted on the main chassis to drive a tape reel of a tape cassette, and a brake unit fixed on the main chassis to help the tension band be in contact with the outer circumference of the reel disc. This can replace a conventional brake unit having a complicated structure, and therefore, the number of component parts can be reduced.

A magnetic recording and reading apparatus includes a noise preventing member provided to at least one of a deck and a holder to cover an upper side of a head drum. Noise generated by the contact between the head drum and the magnetic tape is substantially prevented from being transmitted outside of the magnetic recording and reading apparatus and to a microphone in recording operation, thereby improving the quality of recorded sound.

The plasma display panel comprises two substrates onto which parallel cathodes and anodes are attached, respectively. When the anode and cathode substrates are connected together by barriers, which also prevent the cross-talk between pixels, the cathodes and anodes are perpendicular to each other. The cathodes are made of thin metallic wires that attach to the rear substrate. Fabricating the cathode structure comprises the steps of: preparing a compound fiber in which a plurality of metallic lines are arranged in parallel and a plurality of thermoplastic threads are arranged perpendicular to the metallic lines; placing the compound fiber on the rear substrate; and baking this combination.

A smear noise eradication method in a charge-coupled device (CCD) type camera comprises the steps of inputting respective image signals from one pair of CCD image pick-up devices whose lengthwise directions of corresponding vertical CCDs are perpendicularly disposed with respect to each other, and which are installed on an optical path, and eradicating smear noise after comparing the one pair of image signals according to corresponding pixels. Using the one pair of CCD image pick-up devices, the image signals of the CCD image pick-up devices are compared with each other. When the smear noise is generated, it is eradicated to obtain a high quality image signal.
