DIGITAL DATA RECORDING DEVICE, DIGITAL DATA REPRODUCING DEVICE AND DIGITAL DATA RECORDING AND REPRODUCING DEVICE
Document Type and Number:
Japanese Patent JPH09153201
Kind Code:
A
Abstract:
To provide the digital data recording device in which the recording density is greatly improved.
The digital data supplied from an input terminal 3 are supplied to a multilevel processing circuit 4 and become multilevel data. The data are supplied to an analog waveforming circuit 5 and become analog waveform signals. The signals are supplied to an AM modulating circuit 6 and become AM modulated signals. The signals are then supplied to a writing section 9 which consists of a recording processing circuit 7 that is a recording amplifer and a recording head 8. Then, the signals are recorded on a magnetic tape 10 by a recording head 8.
