Abstract
Abstract A recording/reproducing system according to this invention for use in, for example, a digital audio tape recorder is applied to a type in which recording of an input information signal on a recording medium is restricted, and can ensure releasing of the recording restriction by using release-signal-holding mediums on which a release signal for releasing the recording restriction is recorded. In this case, the release signal is affixed with frequency data for restricting the quantity of the information signal to be recorded on recording medium, and this frequency data is updated in such a way that the greater the number of recording the information signal on recording medium, the smaller the recordable quantity of the information signal.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
69 words
A release signal holding medium for use in a system in which recording of an information signal on a recording medium is restricted comprising: a release signal recording medium physically separate from the recording medium on which the information signal is recorded; and a release signal, recorded on said release signal recording medium, for releasing the restriction of the recording of said information signal on said information recording medium.
Claim 2
Dependent Claim
69 words
A release signal holding medium for use in a system in which recording of an information signal on a recording medium is restricted comprising: a release signal recording medium physically separate from the recording medium on which the information signal is recorded; and a release signal, recorded on said release signal recording medium, for releasing the restriction of the recording of said information signal on said information recording medium.
Claim 3
Dependent Claim
20 words
A release signal holding medium according to claim 1, wherein said release signal holding medium is composed of a card.
Claim 4
Dependent Claim
20 words
A release signal holding medium according to claim 1, wherein said release signal holding medium is composed of a tape.
Claim 5
Dependent Claim
94 words
A release signal holding medium for use in a system in which recording of an information signal on a recording medium is restricted comprising: a release signal holding medium; a release signal recorded on the release signal holding medium for releasing the restriction of the recording of said information signal on said recording medium; and frequency data recorded on the release signal holding medium for restricting a quantity of information contained in said information signal which is to be recorded on said recording medium while the recording restriction is released by said release signal.
Claim 6
Dependent Claim
94 words
A release signal holding medium for use in a system in which recording of an information signal on a recording medium is restricted comprising: a release signal holding medium; a release signal recorded on the release signal holding medium for releasing the restriction of the recording of said information signal on said recording medium; and frequency data recorded on the release signal holding medium for restricting a quantity of information contained in said information signal which is to be recorded on said recording medium while the recording restriction is released by said release signal.
Claim 7
Dependent Claim
20 words
A release signal holding medium according to claim 4, wherein said release signal holding medium is composed of a card.
Claim 8
Dependent Claim
20 words
A release signal holding medium according to claim 4, wherein said release signal holding medium is composed of a tape.
Claim 9
Dependent Claim
112 words
A release signal distribution device for use with a recording apparatus which includes restricting means for restricting the recording of an information signal and releasing means for releasing the restriction on recording of the information signal comprising: a storage medium holding a release signal while engaged and disengaged from the recording apparatus and physically unconnected with a medium holding the information signal; and a housing holding the storage medium when in both engaged and disengaged relations with the recording apparatus, the release signal recorded on the storage medium activating the releasing means to release the restriction on recording of the information signal when the storage medium is engaged with the recording apparatus.
Claim 10
Dependent Claim
112 words
A release signal distribution device for use with a recording apparatus which includes restricting means for restricting the recording of an information signal and releasing means for releasing the restriction on recording of the information signal comprising: a storage medium holding a release signal while engaged and disengaged from the recording apparatus and physically unconnected with a medium holding the information signal; and a housing holding the storage medium when in both engaged and disengaged relations with the recording apparatus, the release signal recorded on the storage medium activating the releasing means to release the restriction on recording of the information signal when the storage medium is engaged with the recording apparatus.
