MD Data stands for MiniDisc-Data, and is a magneto-optical medium for storing computer data. Sony wanted MD Data to replace floppy disks, but the Zip drive from Iomega ended up filling that market need and, later on, the advent of affordable CD-writers and very cheap blank CD media, coupled with the availability of memory sticks and cards proved the final straw for MD-Data. The technology provided 140 MB of data storage, but it was slow and expensive. Also, data drives can only read or write audio MDs when set in "play" mode, which, however, does not provide computer access to the data.

  • MD Data stands for MiniDisc-Data, and is a magneto-optical medium for storing computer data. Sony wanted MD Data to replace floppy disks, but the Zip drive from Iomega ended up filling that market need and, later on, the advent of affordable CD-writers and very cheap blank CD media, coupled with the availability of memory sticks and cards proved the final straw for MD-Data. The technology provided 140 MB of data storage, but it was slow and expensive. Also, data drives can only read or write audio MDs when set in "play" mode, which, however, does not provide computer access to the data. MD Data appeared in products such as an MD still camera and an MD document scanner. MD Data was also used in the late 1990s in 4- and 8-track multitrack recording decks. Meant as a step up from the popular 4-track cassette-based studios, these recorders enjoyed a brief prominence before they were replaced by relatively affordable -- and far more flexible -- direct-to-hard drive recording on Windows and Macintosh based computers. The format has always been hampered by the lack of an affordable MD-Data drive with which to manipulate and back up data using a PC. In 1997, Sony introduced the MD-Data2 format, which could hold 650 MB of data (as opposed to MD-Data's 140 MB). However this format was only used by Sony's DCM-M1 camcorder (capable of still images and MPEG-2 video), and a few multitrack "portastudio"-style audio recorders such as Sony's MDM-X4 and Tascam's 564, among others. The introduction of Hi-MD in 2004 allowed any type of data (files, music, etc.) to be stored on a Hi-MD formatted MiniDisc. This allows for storage capacity of around 340MB on a standard MiniDisc and approx. 1GB on a new, higher-density Hi-MD. (en)
  • MD Data signifiant MiniDisc-Data est un dispositif optique de stockage de données. Sony voulait que le MD Data remplace les disquettes, mais le lecteur Zip de Iomega remplis les besoins du marché et, plus tard, l'arrivée de graveurs de CD abordables et de CD vierges très bon marché, couplé avec la disponibilité des cartes mémoires ont terminé d'achever les MD Data. Cette technologie fournissait 140 Mo de capacité, mais était lente et chère. De plus, les lecteurs ne pouvaient que lire ou écrire des MiniDiscs audio quand ils étaient en mode "play", qui, cependant, n'offrait pas un accès des données par ordinateur. Les MD Data ont été utilisés dans des produits tels que des appareils photos ou des scanners. Les MD Data étaient également utilisés dans la fin des années 90.Ce format a toujours été entravé par le manque de lecteurs de MD Data abordables permettant de manipuler et sauvegarder des données avec un PC. Le format MD Data a été surpassé par l'utilisation du NetMD pour le stockage de n'importe quel type de données sur un MiniDisc audio.Avec l'introduction du Hi-MD à la fin de l'année 2004, l'utilisation de cette fonctionnalité a été relancée par la capacité de stockage d'approximativement 340 Mo pour les MiniDiscs normaux et approximativement 1 Go pour les nouveaux MiniDiscs à haute densité.

  • L'MD Data è una tipologia standardizzata di disco magneto-ottico progettata per contenere video digitale, audio digitale, fotografie digitali e software. È quindi anche una tipologia standardizzata di supporto video, di supporto audio, di supporto fotografico e di supporto informatico. L'MD Data è stato sviluppato e standardizzato dalla Sony partendo dal MiniDisc, ed è stato commercializzato a partire dal 1993. Evoluzione dell'MD Data è l'Hi-MD, commercializzato a partire dal 2004.

  • MD Data或MD-Data的全文為MiniDisc-Data,是一種用來儲存電腦資料的磁光碟媒體(magneto-optical medium),由Sony於1993年發表。Sony原先期望用MD Data取代軟碟片,不過艾美加(Iomega)的Zip軟碟機填補了這個市場的需求,之後又出現價位逐漸可被人接受的CD-R光碟燒錄器以及相當低廉的空白可燒錄光碟片,最後記憶卡的普及成為壓垮駱駝的最後一根稻草,使MD-Data始終無法成為主流的電腦儲存媒體。 一張MD Data碟片可提供140MB的資料儲存量,不過其存取效率緩慢且價格昂貴;此外,其存取碟機在播放模式時只能讀取或寫入MD音樂碟片,而不能供電腦存取資料。這表示:MD音樂片(MD)與MD資料片(MD Data)被硬是區分,無法彈性混用。 Sony發表MD Data後的不久,也推出了相關的應用週邊產品,如MD型照相機或MD型文件掃描器等。到了1990年代後期,MD Data也能使用4軌及8軌的多軌記錄層,這意味著使用MD Data的MD型錄音設備可加速取代已普遍用於錄音工作室中的4軌帶匣錄音設備,不僅更低廉且更為彈性,同時在Windows電腦、Macintosh電腦上更可將錄音直接送入硬碟中。不過,MD Data的儲存記錄格式卻阻礙了MD Data碟機的推行(即便MD Data碟機相當簡單易用),同時也阻礙將MD Data用於電腦資料備份的運用推行。 2004年底,Hi-MD出現,允許在一張Hi-MD格式的MD碟片上儲存各種型態的資料(檔案、音樂、圖像等),且能讓標準MD達到約305MB的儲存容量,在新款的高密度Hi-MD碟片上更可達1GB容量。 附帶一提的是,1997年Sony推出過第二代的MD Data,稱為MD Data2,單片容量從140MB增至650MB,不過只用於MD型攝影機中(1999年發表的Sony DCM-M1),然而該攝影機的銷售並不久。 (zh)
