Description
 
The DAT deck which carries the possible wide band (HS:High Sampling) mode of a 96kHz high sampling.

The wide band mode raised even to 96kHz which is the twice conventional 48kHz sampling is adopted. This expanded a range to the super-high region, and a smooth sound of a wide band mode no one but has been obtained.
In wide band mode, the Recording play over 40kHz is possible by operating signal-processing LSI, a capstan motor, and a drum motor by the twice of a canonical mode. Moreover, in wide band mode, in order to make it run a tapes at a twice as many speed as this, the record time serves as half.
(Wide band HS mode changes a name by the same functionality as the WIDE mode of D-07)

In order to bring close to a more nearly original signal wave form, legato linking conversion is carried.
This performs digital signal processing based on the signal recorded on the tapes, and has the structure of obtaining a play of the sound near the original before recording on a tapes, by connecting between datas with a smooth function curve. Moreover, the original signal before a register is presumed, reappearance with a sound of 20kHz or more is also enabled according to a 1/f damping characteristics, and the play of a more natural sound is aimed at.

(LP) mode is carried for a long time which realizes twice as many sound-recording time as standard (SP) mode at the time of an analog input sound recording and a digital input sound recording with a sampling frequency of 32kHz. If it is a 120-minute type tapes by this, the succession sound recording of a maximum of 4 hours is possible.

The high-output AT head is adopted as a head.
The tapes touch stabilized by being a head of the All Track structure which performed a 20-micrometer uniform track manipulation to the trances orientation of a track, carrying out the welding of the glass to head each sides, and carrying out wear-resistant reservation, and also performing a special polishing manipulation to a gap is realized.

The newly developed 1-bit wide-range linear analog-to-digital converter and 1 bit of high speed pulse flow digital analog converter are adopted as a translation part. A 1-bit scheme is excellent in a linearity, and has the distinctive characteristics that no occurrence of nonlinear distortion or zero cross distortion is theoretically, the translation error at the time of a minute signal is reduced, and the modification of a linearity is achieved.

The TOC 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 DAT.

The high-speed A.I. Artificial Intelligence search and the sub-code application functionality were carried, the sub-code intelligence recorded on the tapes was read, the music numbering and the staring point of music were learned, and a maximum of about 300 times (they are about 600 times at the time of LP) as high-speed A.I. Artificial Intelligence searches are realized using these.
Moreover, when flying various kinds of time intelligences, start ID which shows the start of music, and a fraction not to hear, and the end of convenient skip ID, a pole numbering intelligence, or a register is shown, a register and erasure of ID etc. are possible.

It is possible to register the datas of the music name of a maximum of 60 characters, a player, memo writing, etc. at the beginning of music (start ID fraction). One of remote control and the main units can also perform a register of a data, and the recorded intelligence indicates by scrolling at a counter indicator at the time of the start of each music.

The compact disk-Q code synchro start ID recording function is carried, and the automatic register of the start ID can be carried out with the track number in the compact disk-Q code data transmitted to D-05 with a digital interface, and an index at the time of the digital input sound recording from compact disk.

In order to eliminate the ill effect by the shake of a clock signal, the clean clock circuit into which an audio system and a digital system make a clock signal divide is adopted.
S/N and the distortion are improved by carrying out the oscillation of the clock which controls a system itself to a clearance, and driving it independently by this.

The honeycomb chassis excellent in the periodic-damping property is adopted as a chassis, a weight balance is raised by considering it as the mid ship structure which has arranged the drive in the central part, and the oscillation and the vibration are suppressed.
Furthermore, in order to suppress a cassette half's oscillation effectively, the cassette half is firmly fixed by carrying the original cassette stabilizer of Pioneer, and putting with the special rubber of the upper and lower sides of a cassette half, and also holding down by the resin of two right and left.

The last memory functionality is carried, and the status of on/off of AUTO ID and an input switching is recorded even if it turns off the power.

The parts selected carefully are adopted in order to correspond to wide band-ization.
