<p>A device of the same general physical size and shape as a standard audio cassette tape, but which accepts digital information from any of a variety of sources - including for example: Internet transmission, a digital computer, or memory cards (especially digital memory cards) - and plays this digital information through any, for example, standard audio tape cassette player. The device operates by converting the digital representation of the sound into magnetic signals which are presented to the read/write head of the cassette player equipment. The device allows the user of the cassette player to regulate the audio playback using conventional equipment controls such as: START, STOP, REWIND, FAST REWIND, FORWARD, FAST FORWARD, etc. In one exemplary implementation, the device has the same general physical dimensions of a standard audio cassette; at least one digital processor; and a slot into which electronic media such as, for example, memory cards, smart cards having a processor and a memory embodied thereon and other memory media may be inserted. The device also includes user input control buttons, a display and a headphone jack all mounted in the case of the cassette device such that they are substantially flush with the case and will not interfere with the use in a cassette player. The user can use the cassette device in a cassette player and also use the cassette device as a portable and free standing, digital audio player.</p> |
