Période

THIS RECORDER USED C. 1996-2000.

Canada

ORIGINALLY DESIGNED FOR THE MASS MARKET, MINIDISC HAS BEEN USED AS A PORTABLE PLAYER FOR MUSIC COPIED FROM CDS OR FROM MP3 FILES AVAILABLE ON THE INTERNET. THE ARTIFACT, HOWEVER,WAS USED BY CBC RADIO NEWS REPORTERS FOR NEWS GATHERING. IN THE NEWSROOM, THE REPORTER DOWNLOADED FILES TO HIS OR HER COMPUTER WORKSTATION, WHERE THEY COULD BE EDITED FOR NEWSCAST USING "DALET" SOFTWARE AND STORED ON A SERVER FOR DISTRIBUTION OVER A LOCAL AREA NETWORK. THIS ALLOWED THE PRODUCTION OF NEWSCASTS TO BE LARGELY AUTOMATED, WITH REPORTERS AND PRODUCERS USING COMPUTER SOFTWARE TO PERFORM MANY TASKS ONCE DONE BY TECHNICIANS." (Ref. 1)

Fonction

TO RECORD AUDIO INPUT AS COMPRESSED DIGITAL DATA ON A MAGNETO-OPTICAL DISC.

Technique

INTRODUCED C. 1992, MINIDISC EMPLOYS A MAGNETO-OPTICAL MEDIUM THAT IS RECORDED AND ERASED USING A LASER AND A MAGNETIC HEAD. THE LASER ALTERS THE MAGNETIC COERCITIVITY TO ERASE THE PREVIOUS DATA, ALLOWING THE MAGNETIC HEAD TO THEN IMPART A NEW BIT PATTERN THROUGH POSITIVE OR NEGATIVE POLARIZATION. MINIDISC EMPLOYS DIGITAL COMPRESSION TO REDUCE STORAGE REQUIREMENTS BY A FACTOR OF 5 TO 1. ONE MINIDISC CAN HOLD 74 MINUTES OF SOUND. BY RECORDING ON A DISC, RANDOM ACCESS IS POSSIBLE, MAKING MINIDISC MORE SUITED THAN TAPE TO EDITING ON A COMPUTER WORKSTATION. " (Ref. 1)
