AC Servo
Capstan Motor and GX head characteristics assure complete tape travel stability and long
lasting performance. Automatic and Manual Reverse Playback.
Integrated
Akai Quality Features for Unparalleled Performance
New AC Servo
Motor
The new Akai
AC Servo Motor employed in this model for direct capstan drive is equipped with
114 gears on both the rotor and stator sides and a detector coil and magnet are
built in on the stator side for a completely new pulse detection system. With
this system, pluse detection is made only once every 114 pluses instead of at
each pulse for greatly increased pulse output.
Symmetrical
head Block, Impedance Roller, and tension Arms for even tape travel in both
directions.
For
perfectly equal tape speed and even tape tension is both directions, the head
block layout is of symmetrical design and the machine is equipped with an
impedance roller and tension arms. These features function together as integral
parts of this GX Head, AC Servo Motor system for unparalleled stability and
long-lasting quality performance.
Automatic
and Manual Reverse Playback.
Automatic
Reverse Playback is as simple as applying a piece of sensing foil to the tape
at desired reversing point. Manual Reverse Buttons can be operated at any time during plauback.
All GX heads
One each GX
Forward Playback, GX Reverse Playback, and combination GX Recording/Erase head guarantees long
lasting performance. As is well known, the core of these heads are made of
single crystal and are mounted and set in glass. The wear-free characteristics
of these materials permit a perfectly lineal head gap for a "focused
field" system and optimum head-to-tape contact which results in a wider
dynamic range with excellent Signal-to-Noise ratio.
