Definitions

• the present invention has for its object to use this technology not only for the exchange of data between a smart cassette and an EDP device, but for use as a digital "magnetic tape" cassette in connection with conventional cassette recorders.
• This object is achieved in that the SmartKassette with a magnetic interface in the form of a digital / analogue changer for playing music via a conventional analog cassette recorder, an analogue / digital changer for recording music via a conventional analog cassette recorder, one digital interface for recording the SmartCassette in digital form, a sensor near the 'magnetic head, so that the SmartDiskette can determine whether music should be played / played or whether fast forward / backward should be rewound, a plug connection for the power supply of the electronic components of the Smart ⁇ cassette while recording with digitized music and for simultaneous charging of the optionally available battery and a processor and digital memory in appropriate technology for storing the digitized music.
• CD compact disc
• MD mini disc
• DAT digital audio tape
• DCC digital compact cassette
• the digital / analog converter via which the digitally recorded pieces of music are transmitted without loss of content, serves as an interface to conventional cassette recorders.
• Convention tape recorders too Music can be recorded on the SmartCassette, but in this case only with a slightly better quality than on conventional magnetic tape cassettes.
• FIG. 1 shows a SmartKassette 1 with magnetic interface 2, analog / digital and digital / analog andler with amplifier 3, which is connected to the processor 4 of the SmartKassette, memory chips 5, which are connected to the processor 4 and are used for storing the digitized music, rotor 6, which is driven by the standard drive technology of a cassette recorder, stator 7, which is connected to the current regulator 8 and which supplies the current required for the electronic components when playing music, plug contacts 9 as a current interface which the electronic components when importing digitized music via the digital interface 11 with the required power, battery 10 in order to supply the electronic components with power even when the smart cassette is not in a player / player and a sensor 12 so that the Processor can determine whether music should be played or whether to another Ren music piece should be fast forwarded or rewound.
• Figure 2 shows
• the current interface 15 is connected to the power supply 16 of the device 13.
• the digital interface 14 is connected to the processor 17 of the device 13, which in turn is connected to other components of the device 13, not shown.
• the digitized music present in the device 13 is compressed in the processor 17 of the device 13 according to known methods such as MPEG or ATRAC and loaded into the processor 4 of the smart cassette via the digital interface 14/11. However, it is also possible to compress the digitized music in the processor 4 of the smart cassette 1 according to the known methods.
• a file system is managed in the processor 4 of the smart cassette 1 and the digitized information is stored in the memory elements 5. Since more current is required to store the information than can be generated by the current generator 6, 1, the electronic components of the smart cassette 1 are supplied with additional current from the device 13 via the current interface 15/9 during this process provided. Play digitized music on a conventional tape recorder
• the smart cassette 1 is inserted into the drive of the cassette recorder.
• the drive 6 moves, current is generated via the current generator 6, 7 and the processor 4 is fed via the current regulator 8.
• the processor 4 knows whether the music pieces should be selected forwards or backwards.
• the sensor 12 reports to the processor 4 that the read / write head of the cassette recorder has lowered, the processor 4 knows that music should be played.
• the memory modules 5 are accessed on the basis of the file system and the corresponding piece of music is selected. The information received by the memory modules 5 is decompressed in the processor 4 according to the known compression methods and passed on to the digital / analog converter 3.
• the signals are converted, amplified and passed on to the magnetic interface 2 as analog signals.
• the read / write head of a conventional cassette recorder receives the signals as if they came from a magnetic tape, but not in the quality customary for magnetic tapes, but in the quality customary for digital sound carriers.
• the processor 4 of the smart cassette 1 detects this in that either the right-hand current generator 6, 7 or the left-hand current generator 6, 7 supplies the current and further that the sensor 12 does not report the lowering of the read / write head of the cassette recorder. In this case, the processor uses the file system to select the next or the previous piece of music, depending on which power generator 6,7 supplies the power. Record music on a conventional tape recorder
• the smart cassette 1 is inserted into the drive of the cassette recorder.
• the drive 6 moves, current is generated via the current generator 6, 7 and the processor 4 is fed via the current regulator 8.
• the processor 4 knows that music should be played or recorded.
• the processor 4 receives signals via the magnetic interface 2 and the analog / digital converter, it knows that music should be played.
• the received signals are compressed using a conventional compression method and the digitized information is stored in the memory elements 5 via a file system.
• Pieces of music with a running time of several hours can be played.
