    • A prerecorded cassette (1) belongs to a system for magnetically recording/reproducing signals on/from magnetic tape in accordance with a standard, which system comprises apparatuses and cassettes compatible therewith, which cassettes comprise two parallel main walls and interconnecting transverse walls and occur with prerecorded tape (prerecorded cassettes 1) and with blank tape (blank cassettes 3), which standard specifies a tape length marking which can be detected by an apparatus and which marks the length of the magnetic tape in a cassette by a pattern of openings (33-37) in a marking zone (39) of a main wall (19) of a cassette (3), which tape length marking comprises a plurality of submarkings (33-37) in a binary multi-bit code, the value of each bit being defined by the presence/absence of an opening.
      With the prerecorded cassettes (1) a tape length marking is dispensed with completely and information about the playing time and information about the position on the tape are recorded on the tape as time code. Preferably, the system specification for the erase protection is such that, to indicate the impossibility of home recording, the prerecorded cassette does not have an erase protection opening at all. As a consequence, the prerecorded cassette (1) is not suitable, and can hardly be made suitable, for home recording. If the cassette is provided with a permanent label (55) the relationship between the recording and the information on the label will be maintained for the entire life of the cassette.

    • In a tape cartridge, a pair of rib members 5 are projected inward from the inner surface of an upper half 1a of a case body 1 as one body for regulating the right and left tape reel hubs 3, and there is provided a transparent window portion 4 of a laterally elongated shape with a narrow width w smaller than the minor diameter of each of the rib members 5, extending across the rib members 5. And there are provided right and left window connecting members 13 extending frontward from the right and left edges of the window portion 4 along on the inner surface of the case body 1 as one body and there are provided right and left prism members 14 for detecting an end of a tape, connected as one body with the front edges of the respective window connecting members 13, so that both of the right and left hubs 3 can be seen at the same time with reference to each other.

    • Cassette for recording tape or other medium, typically a VHS video tape cassette, has built-in control means (18, 30) including a stop element (56) acting automatically to prevent a winding or rewinding operation of the tape or other medium (14) whereby a user can effect a single play through of the tape or medium only; the cassette also including a key operated or other coded lock (60) which has to be operated e.g. by a video library or other control authority to reset the control means for further operation of the cassette. A tamper-­proof counter (52) is also preferably incorporated to record the number of times the tape or other medium has been played. The invention enables video hire charges to be related to the number of playings of a tape for example.
    • 用于记录磁带或其他介质(通常为VHS磁带盒)的盒式磁带具有内置的控制装置(18,30),其包括自动地起作用以阻止磁带或其它介质(14)的卷绕或重绕操作的停止元件(56) ),由此用户只能通过磁带或介质实现单个播放; 该盒还包括键操作或其他编码锁(60),其必须被操作。 通过视频库或其他控制权限来重置用于盒的进一步操作的控制装置。 还优选地结合防篡改计数器(52)以记录带或其他介质的播放次数。 本发明使视频租用费用与例如磁带的播放次数相关。
