Precision Recording Technology

Precision Recording Technology addresses the key areas that

influence the quality of DVD writing. It comprises:

Liquid Crystal Tilt Technology

A Liquid Crystal Tilt device helps to ensure precise writing onto the

surface of discs by automatically compensating for media that have

become warped or are of uneven thickness.

Ultra DRA (Dynamic
Resonance Absorber)

DRA absorbs vibrations caused

by imbalanced discs to stabilise

them for enhanced quality of

writing and read performance

even at higher speed.

QuietDrive

75% reduction in
operational noise

It is to be expected that the

company behind the DVD-R/RW

format will continue to lead the

development of DVD technology.

Pioneer does not disappoint with

the new QuietDrive.  Consumer

operational noise from many

high speed DVD writers is

noticeable.  The sound is created

by vibrations caused as the DVD’s

rotation speed accelerates to

support faster reading / writing.

Showcased for the first time in

the DVR-A07XL, QuietDrive

reduces ambient noise.  It works

by incorporating a honeycomb

structure on the drive’s casing

that dissipates vibrations.  Sound

proofing pads inside the housing

also soak up excess noise.

Performance Adjusting
Firmware

Performance Adjusting Firmware

intelligently reduces the rotation

of the disc depending on the

application.  During DVD Video

and Audio CD playback when

ambient noise must be kept to a

minimum the firmware adjusts

the speed accordingly.  Without

the need for a fan, QuietDrive

and Performance Adjusting

Firmware reduce ambient noise

by 75% over previous Pioneer

models.

Because the lengths of the left and right
beams are equal, the focal point is accurate.

If the disc is warped or its thickness is
scattered, it cannot form a precise beam
spot, preventing accurate writing.

Forms a beam spot that is uniform on the
left and right sides, achieving accurate writing.

Smart Laser Driver

The circuitry that controls the writing of DVDs is traditionally

positioned on the drive’s main circuit board.  In the DVR-A07XL

this has been moved to the laser pick up assembly.  The feature

prevents any signal distortion between the main board and the

laser driver to improve writing accuracy.

Distributed Real Time Defect Management (DRT-DM)*

The DVR-A07XL uses DRT-DM which supports recording under

optimum conditions to ensure precision writing to DVD discs – even

those that have been written to many times.  The feature also helps

reduce the degradation in disc quality that can occur over time.
