Abstract: An information reproduction system that provides an apparatus for reproducing audio/video information from an information recording medium having a tape form for example and circumventing problems associated with illegal copies of information recording media. If a match is found between the contents of identification data information read from a memory fixed to a cassette incorporating a magnetic tape and the contents of individual key data information stored in an information storage memory, a controller causes an information reproducing block to reproduce main information from the magnetic tape.

Abstract: A non-contacting-type information storing device is stuck to the adherent surface of the object, and includes a storing means for storing the stated information and an antenna which has the stated loop form and which is connected to the storing means. The non-contacting-type information storing device further includes a magnetism absorbing plate which is made from high-permeable material and which is placed so that it is interposed between the adherent surface of the object and the antenna at the time when the information storing device is stuck to the adherent surface of the object. As a result, it is possible to provide a non-contacting-type information storing device in which the modulated magnetic-field given from the exterior can be absorbed by the antenna without being leaked to the adherent surface of the object even though the adherent surface of the object is made of metal. Thus the information can be read irrespective of the type of the material of the adherent surface of the object.

Abstract: A cassette label comprising, an integrated circuit comprising a memory unit and a signal processing unit, an antenna members for carrying out at least a transfer of signals with respect to the integrated circuit, and a label body accommodating the integrated circuit and the antenna members and mounted on a back surface of a video cassette tape, and a video cassette tape comprising, a video tape for recording video signals, a cassette case for accommodating the video tape, and the cassette label mounted on the back surface of the cassette case.

Abstract: In a tape recording and/or reproducing apparatus having a guide drum with rotary heads for recording or reproducing signals in slant tracks scanned on a longitudinally transported tape wrapped helically about a circumferential surface of the drum between a tape-entry position and a tape-exit position; a tape-guiding assembly, which may be part of a tape loading device, includes ultrasonically vibrated tape guides engageably by the tape adjacent the tape-entry and tape-exit positions, respectively, auxiliary guide elements angled relative to the vibrated tape guides, respectively, and each being disposed for engagement by the tape between the respective vibrated tape guide and the tape-entry or tape exit position, respectively, with such auxiliary guide elements having respective surface projections extending therefrom at positions therealong corresponding to widthwise portions of the tape at which the rotary heads scan the tape adjacent the tape-entry and tape-exit positions, respectively, so that the surface
