Abstract: A tape cartridge housing a magnetic tape includes an auxiliary storage medium having a storage unit in which to store the recording medium information such as design parameters or the number of times of recording and/or reproduction of the magnetic tape, and a transmission/reception unit for effecting inputting/outputting of the recording medium information with the recording and/or reproducing apparatus. The auxiliary storage medium is mounted so that the transmission/reception unit is exposed to outside through an opening provided in a lateral surface of the main cartridge body unit not obstructing the loading of the magnetic tape, that is in a surface of the main cartridge body unit other than its front surface as an inserting end of the tape cartridge into the inside of the recording and/or reproducing apparatus. The auxiliary storage medium has an antenna constituting the transmission/reception unit for inputting/outputting the recording medium information with the recording and/or reproducing apparatus. It is through this antenna that the power is supplied from the auxiliary recording and/or reproducing unit provided on the recording and/or reproducing apparatus in accordance with a non-contact system transmitting the recording medium information and the power overlaid on the recording medium information.

Abstract: A tape cartridge holding a magnetic tape has an auxiliary storage medium that includes a storage section where recording-medium information such as the specifications of the magnetic tape and the numbers of recordings and reproductions on and from the magnetic tape and a transmitting/receiving section for inputting/outputting recording-medium information to/from a recording/reproducing device in a noncontact way, namely by radio. The storage section and transmitting/receiving sections are provided in such a way that the transmitting/receiving section faces outside through an opening provided in a side of the cartridge body. The side is a side except for the front side which is the forward side when the tape cartridge is loaded into the recording/reproducing device, and does not obstruct the loading of the magnetic tape. The auxiliary storage medium includes an antenna that constitutes the transmitting/receiving section. Through the antenna, electric power is supplied from the auxiliary recording/reproducing section of the recording/reproduction device in a noncontact way in which the recording-medium information and power are superposed and transmitted.

Abstract: PROBLEM TO BE SOLVED: To make a magnetic tape usable as fixing type recording media similar to a hard disk and also to prevent the heat accumulation in the case by housing the magnetic tape, running drive means and recording/reproducing means in one case and also providing an air agitating means. SOLUTION: By the recording/reproducing device 1 with built-in magnetic tape, the magnetic tape 5 primarily to be used as the removable media is used as the fixing type recording media similar to the hard disk. Therefore, a loading mechanism, etc., are eliminated and also the dustproof effect is increased since the magnetic tape 5 is incorporated in the hermetically sealed case 2. Further, reel motor fans 29 directly connected to spindles 6a, 7a of supply and take-up reel motors 6, 7 are provided. By these arrangements, the reel motors 6, 7 and a motor circuit board 22 are cooled, and also the warm air accumulated in the local part of the hermetically sealed case 2 inside is cooled by agitating it to disperse in the wide area.

Abstract: PURPOSE: To simultaneously record two independent video signals on one recording medium and to reproduce the two recorded video signals in changing them easily. CONSTITUTION: The device is provided with a recording control means for controlling recording operation of the video signals S10 and S11, and by recording the independent 1st and 2nd video signals S10 and S11 alternately on the recording medium 2 in a field unit or a frame unit, the independent 1st and 2nd video signals S10 and S11 can simultaneously be recorded on one recording medium 2. Thus, by alternately recording the 1st and 2nd video signals S10 and S11 on the recording medium 2 in the field unit or the frame unit, at the reproducing time, the video signals S10 and S11 to be reproduced can easily be changed in changing only read-out positions of the recording medium 2.

Abstract: PURPOSE:To effectively clean dirt such as magnetic powder. etc., by supporting freely rotatably the shaft of a cleaning roller and laminating and fixing a lot of sheet members having disk shapes in axial direction on sleeves. CONSTITUTION:The axial center line 45 of the rotary shaft of the cleaning roller 41 of the edge part of a cleaning roller arranging part 36 is made to have a prescribed angle theta with the axial center line 46 of the rotary shaft of a rotary drum 5. Consequently, sheet members 43, 43..., of the roller 41 are abutted obliquely with the outer peripheral surface of the rotary drum 5 and tape contaction surfaces 6a, 6a... of magnetic heads 6, 6... s a and even though the roller 41 is rotated by being accompanied by the rotation of the drum 5. a cleaning effect is not reduced extremely because the rotational speed becomes relatively sllower than that of the drum 5, Furthermore, the cleaning of magnetic heads 6, 6... is effectively performed because the roller 41 is a roller made by laminating a lot of sheet members 43, 43... a in the axial direction of the roller, respective sheet members 43, 43... are abutted with the outer peripheral surface of the drum 5 and the tape contaction surfaces of 6a, 6a... of magnetic heads 6, 6... while being bent.

Abstract: PROBLEM TO BE SOLVED: To prevent the damage of a magnetic tape which is generated at the outer circumferential edge part of a tape lead plane by forming a chamfered surface such as slope, roundness and so forth at the outer circumferential part of the tape lead plane guiding the edge of one side of a magnetic tape in a helical state. SOLUTION: A slope 8 or a roundness or a chamfered surface similar to them is formed at outer circumferential edge part 7a of the tape lead plane 7 of a fixed drum 5 by cutting the edge part 7a with a chamfering work. At the time of loading and unloading a magnetic tape 12, when the tape slides up upon the tape lead plane 7 from the direction of the arrow a1 against a downward slide energizing force F or the tape slides down below the plane 7 to the direction of the arrow b1 by a downward slide energizing force F, the magnetic tape 12 can be smoothly guided in directions of the arrows a1, b1 by the chamfered worked surface 10 such as slope 8, roundness and so forth.

Abstract: PROBLEM TO BE SOLVED: To use a magnetic tape to as fixing type recording media without considering the interchangeability by housing all of the magnetic tape, running means and recording/reproducing means in one hermetically sealed case. SOLUTION: A pair of tape reels 3, 4, supply/take-up reel motors 6/7, capstan 8, pinch-roller 10, multi-channel rotary head drum 11, tape guides 13, 14, 15, 16, tension regulators 17, 18, etc., are arranged in the hermetically sealed case 2 which is formed by a light metal alloy such as an aluminum, etc., or a heat- resistant synthetic resin, etc. A circuit board for various signal processings, interface with the outside and motor driving is mounted in parallel with the hermetically sealed case 2. Thus, the reliability is increased by accurately controlling the tape tension and acceleration-deceleration, and the recording capacity in the same volume as compared with a hard disk is remarkably increased, then the extreme long time information is recorded.
