Abstract

A recording/reproducing system for use in a digital audio tape recorder using memory functions and a method thereof which are capable of storing reproduced aural signals in a memory bank, and capable of reading and recording the stored aural signals without the use of an additional DAT system. The system includes a memory section for storing signals that are input to a D/A converter from a digital signal processing section, and a memory controlling section for storing signals that are input to the D/A converter from the memory section, and for reading and applying the signals stored in the memory section to the digital signal processing section. As a result, the system and the method for recording/reproducing can duplicate a tape with one DAT by storing reproduced signals in the memory when the DAT is in are producing mode and reading and recording the stored signals in a tape.

Claims6

Dependent claims

A recording and reproducing system for a digital audio tape recording comprising:

a head drum for reproducing and recording first aural signals;
a high frequency amplifier operatively communicative with said head drum for amplifying said first aural signals;
data processing means operatively communicative with said high frequency amplifier for converting said first aural signals to parallel signals;
digital signal processing means operatively communicative with said data processing means for digitally filtering said first aural signals;
a digital-to-analog converter operatively communicative with said digital signal processing means for converting said first aural signals digitally filtered by said digital signal processing means to second aural output analog signals;
an analog-to-digital converter operatively communicative with said digital signal processing means for converting third external aural analog signals input to the recording and reproducing system to fourth digital aural signals;
system controlling means for controlling said digital signal processing means;
a memory section for storing said first aural signals digitally filtered by said digital signal processing means that are also input to said digital-to-analog converter;
and
memory controlling means operatively communicative with said system controlling means, said memory section, said digital signal processing means and said analog-to-digital converter for controlling the storing of said first aural signals that are input to said memory section in response to said system controlling means, and for reading from said memory section said first aural signals stored in said memory section and applying said first aural signals stored in said memory section to said digital signal processing means.
