The DAT deck which carries a 1-bit analog-to-digital
converter and a bit stream digital analog converter.
The newly developed
1-bit analog-to-digital converter and the bit stream digital analog converter
(system-application-architecture7350) are carried in the translation part.
Since this 1-bit scheme does not need to take into consideration problems,
such as an error of an electrical resistor, or gap of timing of operation, as
compared with a multiple bit scheme, it is excellent in a linearity and does not
have an occurrence of nonlinear distortion or zero cross distortion
The completely same device as what is adopted as
digital-analog-converter PD-T07 is adopted, the translation error at the time of
a minute signal is reduced, and the modification of a linearity is aimed at.
In order to eliminate the shake of an important clock signal by a 1-bit
scheme, the clean clock circuit into which the audio system and the digital
system made the clock signal divide is adopted.
High S/N and the
Low-noise-izing are attained by carrying out the oscillation of the clock which
controls a system itself to a clearance, and making it drive independently by
The high-output AT (All Track) head developed by the original precision
technology of Pioneer is carried in the head.
AT structure which
carried out a 20-micrometer uniform track manipulation to the trances
orientation of a track was the distinctive characteristics, AT head carried out
the welding of the glass to each sides in order to raise wear resistance, is
performing special polishing about the gap which is an entrance of a signal, and
has realized the tapes touch stabilized more.
Moreover, little signal reading of an error rate is realized by making
high a play Output voltage of 2-6dB.
LP (long time) mode which realizes twice as many sound-recording time as
SP (standard) mode at the time of an analog input sound recording and a digital
input sound recording with a sampling frequency of 32kHz is carried. Thereby,
the succession sound recording of a maximum of 4 hours is possible on a
The TOC (Jump Table segment of Contents) functionality
which records intelligences, including the time of a special NetWare program,
the length of each music, etc., on the location of the beginning of a tapes is
carried. By this functionality, information management, such as music time of
each [ the number of total music and total time, and ] music, start time of each
music, and residual quantity time of a register fraction, is possible also for
About 300 times (at the time of LP about 600 times) as many A.I.
Artificial Intelligence search functions are carried at the time of the fastest
which utilized the TOC functionality.
This carries functionalities, such as
A.I. Artificial Intelligence search [ using a TOC intelligence ], time skip,
Tip-of-the-Day memory, random play, and fine Cue/Review.
As a time
intelligence, A-Time which shows the lapsed time from the beginning of a tapes,
P-Time which shows the lapsed time from the head of each music, the end mark
which shows the ending point of a sound recording, etc. can be displayed.
The 1.6mm flat chassis which has the flat structure which performed the
special manipulation in a mechanism part was adopted, the unnecessary
oscillation generated by a mechanism was reduced, and the tapes run stabilized
more is realized.
Moreover, the original cassette stabilizer of Pioneer
which suppresses a cassette half's oscillation is carried, and it puts with the
special rubber of the upper and lower sides of a cassette half, and also a
cassette half is firmly fixed by holding down two right and left by a resin, and
the oscillation is reduced.
The large-sized honeycomb insulator
excellent in the periodic-damping property and the honeycomb chassis are adopted
as a chassis.
In order to reduce the ill effect by unnecessary
oscillation of a drum, the structure of the rotating drum was improved from the
origin and the low oscillation and the low undesired-sound structure are adopted.
The direct construction is adopted as an input volume and the
signal from an analog input termination is reducing the failure by leading about
of a signal path in being inputted into an input volume by the shortest
