1. A portable electronic cassette for insertion into a cassette unit designed for receiving magnetic tape based media comprising:
- a cassette housing having the external appearance of a magnetic tape cassette;
a digital memory disposed within said cassette housing for storing digital information;
a digital processor disposed within said cassette housing and coupled to said digital memory;
an interface disposed within said cassette housing for receiving information operated on by said digital processor for generating magnetic signals simulating signals which are generated by a magnetic tape for allowing transfer of said magnetic signals to said cassette unit, where said interface including converter circuitry for converting digital signals transmitted thereto from said digital processor into magnetic signals generated by a magnetic tape, said interface circuitry including a coil; and
a source of electrical energy operatively coupled to at least said digital processor.

25. A method of coupling information between a digital memory and a head of a cassette unit designed for receiving magnetic media comprising the steps of:
-
storing data in a digital memory disposed in a housing having an exterior form being substantially the same as a cassette such that the housing can be inserted into a cassette unit; processing data stored in said memory using digital processing circuitry disposed within said housing and coupled to said digital memory; converting digital signals output from said digital processing circuitry into magnetic signals to simulate signals generated by a magnetic tape; and coupling data between said data transfer device and said cassette unit, wherein said converting and said coupling steps are performed using a coil disposed so as to transfer information to said head of said cassette unit. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
