tape onto a digital compact cassette tape. Similarly,
digital signals from a CD player recorded onto a DCC
in their original form cannot be recorded from the DCC
tape onto a digital audio tape in their original form. in
other words, SCMS restricts the recording of digital
signals even when different digita! recording
equipment such as DAT and DCC are used in
combination.
