Abstract
Cassettes of recording tape are provided with an electronic memory including semi-conductor circuits mounted in the cassette housing for storing data relating to the cassette or tape therein. A memory error signal device is also provided in the cassette housing having states representing that data stored on the cassette memory has an error or no error. Devices for a tape deck apparatus for cooperation with the cassette memory circuits and error signal device are also disclosed.

8. in combination:
-
a cassette of recording tape; said cassette having electronic memory circuits for storing data relating to the cassette or the tape contained in the cassette, tape drive means, controller means for said tape drive means, generating means for producing signals representing tape movement by said drive means, display means operated by said controller means to display instantaneous tape position derived from said signals, means for connecting said controller means to said electronic memory circuits of a cassette received on said tape drive means, said controller means including circuit means operative to write data signals in said memory circuits representing instantaneous tape position derived from signals produced by said generating means, said controller means including circuit means operative to read said memory circuits and provide instantaneous tape position data.
-
- 9. A cassette of recording tape, said cassette including a housing, reel means in said housing for storing tape, an electronic memory including semi-conductor circuits in said housing, said cassette further including a memory signal device in said housing for generating a signal upon operation thereof by mechanism associated with said cassette reel means, said signal representing that data stored in said cassette memory may be in error, and means carried by said cassette housing for cooperation with means on a peripheral device for blocking the generation of said error signal.
- 20. A cassette of recording tape, said cassette including a housing, reel means in said housing for storing tape, an electronic memory including semi-conductor circuits in said housing for storing data relating to said cassette or the tape therein, said cassette further including a memory error signal device in said housing having two states representing that data stored in said cassette memory has no error or has an error, respectively, and means in said cassette housing operable by a peripheral device to set said signal device from said no error to said error representing state.
