Pioneer Develops 16-layer 400GB Blu-ray Disc

Wed, 09 Jul 2008 01:00:00 +0000

Its per-layer capacity is 25 gigabytes, which is the same as that of a Blu-ray Disc (BD). This multilayer technology will also be applicable to multilayer recordable discs. This development has bolstered Pioneer's confidence in the feasibility of a large-capacity optical disc, which is expected to become necessary in the near future.

Utilizing the optical disc production technology that it has developed in the DVD field, Pioneer solved these problems by, among other things, using a disc structure that can reduce crosstalk from adjacent layers, resulting in a 16-layer optical disc that can playback high-quality signals from every layer.

Pioneer achieved stability in the playback of recorded signals by employing a wide-range spherical aberration compensator and light-receiving element that can read out weak signals at a high signal-to-noise ratio in the optical pick-up mechanism.

Since the optical specifications of the objective lens, such as NA (Numerical Aperture), are the same as those for the existing BD discs, it is possible to maintain compatibility between the new 16-layer optical disc and the BD discs.

The 16-layer optical disc technology, capable of storing much more data than the conventional discs on one disc, will greatly reduce the number of discs to be used and therefore contribute to the conservation of resources.

The MEP-7000 can also be setup to playback and mix music automatically using playlists, allowing the system to entertain when no DJ is present.

The Pioneer MEP-7000 and SEP-C1 Software Entertainment Controller are a response to the trend of laptops being utilised by professional DJs.

Key new features to this product type are the 4.3-inch colour LCD screen that gives clear accurate information, allowing intuitive and easy menu navigation.

The MEP-7000 transforms into a Karaoke playback device when a CD-G disc is inserted, displaying the playback video on the LCD screen, but can also be fed to external monitors using the composite video output terminal.

The SEP-C1 works as a software controller when used in conjunction with compatible software such as Pioneer's bundled "DJS". This allows your to manage and control playback of audio files stored on your computer, to give full scale DJ performance without the need for a mouse or keyboard.

The Pioneer MEP-7000 allows USB control from either PC or Mac. So, besides music from CD/DVD, the MEP-7000 lets DJs play music files, such as MP3 /AAC/WAV/AIFF, stored on USB keys, HDD, CD-R/RW and DVD±R/RW.

The unit is also compatible via USB with Pioneer's DJS software or applications such as Serato Scratch LIVE or Traktor - without the need for a time coded disc.

USB connectivity furthermore means that the SEP-C1 can easily be used as a MIDI controller for MIDI-compatible computer applications.

The 4.3-inch colour LCD with high visibility, intelligent Graphic User Interface and a rotary selector enables rapid track searches from huge music libraries.

The high quality Touch Sensor Jog Wheel is capable of controlling various scratch sounds and these definitely broaden the scope of any DJ performance. The MEP-7000 carries 3 patterns of Scratch Jog Effects (SCRATCH, BUBBLE and TRANS) and 3 patterns of Digital Jog Break Effects (JET, ROLL and WAH), which vary depending on the DJ's choice and use of the Jog Wheel .

Effects lovers will be pleased to know there are also 8 patterns of DJS Effect (DELAY, ECHO, AUTO PAN, AUTO TRANCE, AUTO FILTER, FLANGER, REVERB and PITCH SHIFTER) available, and that these can all be synced with the Beat Per Minute, if required.

The MEP-7000 uses an Auto Mix function that allows auto mix playback of tracks registered on the Play List. There are then 4 patterns of Mix Mode (ECHO, ZIP, CUT IN and CROSS FADE), allowing music to be mixed in a selected style and played automatically.
