XDR (eXtended Dynamic Range, also known as SDR (Super Dynamic Range)) is a quality-control and duplication process for the mass-production of pre-recorded audio cassettes. It is a process designed to provide higher quality audio on pre-recorded cassettes by checking the sound quality at all stages of the tape duplication process. In this way, the dynamic range of audio recorded on an XDR-duplicated cassette can be up to 13 decibels greater.[1]
History [link]
XDR was originally developed by Capitol Records-EMI of Canada in 1982 as "SDR" (Super Dynamic Range). Capitol in the USA then adopted the system for its cassette releases that same year, renaming it "XDR".[2]
Process [link]
The XDR/SDR process involves many steps, the most prominent being:
- Duplication of the cassettes from a 1" wide master loop tape mounted in a loop bin duplicator (as opposed to standard cassette duplication using a 1/2" master loop tape), resulting in clearer high frequencies, greater bass response, and less noise.[3]
- Recording a short test toneburst at the beginning and end of the program material on the cassette, to detect for any loss of audio frequencies in the audio spectrum. The toneburst consists of 11 tones about .127 seconds in length (with .023 seconds of silence in-between each tone), from 32 to 18,000 Hz. These tones are recorded on the cassette, and are read during the duplication process to detect if there is any loss of any audio information.[4]
As well as with EMI & Capitol Records, PolyGram and other labels also offered cassette releases duplicated with the XDR process.

History
Uniregistry Corporation was officially founded in 2012 by Frank Schilling, one of the largest private domain name portfolio owners in the world, and registered in the Cayman Islands. However, the domain Uniregistry.com was registered six years earlier and the company filed an intent to use the name in the Cayman Islands in 2010. Trademark applications for the "Uniregistry" mark and its stylized "U" logo were filed in 2012. That year, Schilling invested $60 million and applied for 54 new top-level domains. Uniregistrar Corporation became an ICANN-accredited registrar in February 2013. In January 2014, Uniregistry Inc. became a subsidiary in Newport Beach, California to house a West Coast service and support team. The registrar began operating under the licensed Uniregistry brand name in 2014. Uniregistry's registry infrastructure was designed by Internet Systems Consortium (ISC) and Uniregistry subsequently purchased its infrastructure in 2013.

XDR (video game)
XDR (エックス・ディー・アール) (short for "X-Dazedly-Ray") is a 1990 Japanese shoot 'em up game released for the Sega Mega Drive. It is a sideways scrolling shoot 'em up containing six levels.
Story
On the terrestrial planet Sephiroth, which is home to a variety of peaceful and prosperous advanced societies, an ancient evil has returned. A long time ago, a warmonger known only as Guardia was banished from the planet, but has finally returned with an entire space military. The Guardia Military soon invades Sephiroth and crushes its defenses with its long hardened space technology. Within time, a space fighter was developed to match the power of the Guardia Military. Based on Guardia’s unknown desire for destruction and its own might, the ship was named the "XDR", or "X-Dazedly-Ray".
Gameplay
Players piloted the titular ship through six different checkpoint-heavy levels, blasting various ground and sky forces. Rather than having Bomb weapons, the ship was equipped to fire a variety of different shots and smaller bombs. Players could collect power ups such as different firing weapons, ground-force bombs, a shield and Options, all of which were upgradable to three levels. Players could also change the ship's speed through four variations. Many of the end-level bosses required timed shots in exact hit points similar to Gradius.
