 In October 2004 during Ceatec Japan, DPHI executives stated that the format would return to the consumer market at about half of the original price-per-disk — $4.50 instead of the original $10 for 500 MB — and that new devices are in development to support the use of DataPlay disks as general storage devices, ditching the proprietary DFS for the FAT file system(([[https://web.archive.org/web/20190331213038/https://www.pcworld.com/article/118108/article.html|PC World — DataPlay Discs Stage a Comeback]])). In October 2004 during Ceatec Japan, DPHI executives stated that the format would return to the consumer market at about half of the original price-per-disk — $4.50 instead of the original $10 for 500 MB — and that new devices are in development to support the use of DataPlay disks as general storage devices, ditching the proprietary DFS for the FAT file system(([[https://web.archive.org/web/20190331213038/https://www.pcworld.com/article/118108/article.html|PC World — DataPlay Discs Stage a Comeback]])).

 +One of the only devices to feature DataPlay disks was the iMP-350 SlimX, developed by the Korean company iRiver. This player was rather expensive at ~$350 and showed off a design language reminiscent of its time; complete with translucent plastic, chrome accents, and "futuristic" aesthetic(([[https://web.archive.org/web/20191111145537/https://www.ixbt.com/multimedia/iriver-100.shtml|IXBT — MP3-плеер iRiver iDP-100 на носителях формата DataPlay]])). More manufacturers planned to produce readers and players for the format, but information about most of these models is scant.

 To locate a file, the drive reads system sectors starting with the most recently written one and checks whether it references the desired file. If found, that reference is used and reading stops. If not, the drive proceeds to progressively older sectors until the file is located or all sectors are exhausted. This "most recent wins" approach lets the drive present an accurate, up-to-date view of the file system — including files marked as deleted — despite the underlying inability to erase or move any data once written. To locate a file, the drive reads system sectors starting with the most recently written one and checks whether it references the desired file.

 +Rating: **[[reference:format-death-scale#level_4_🟠_endangered|Level 4 🟠 — Endangered]]** 
 + 
 +As of now, there are no official channels in which to purchase DataPlay disks, readers, or players and all have been out of production for over two decades. The only eBay listings I could find for NOS disks(({{wiki:docs:ebay_307164516550_dataplay-disks.pdf|eBay — DataPlay Disk [Archive Listing]}})) and optical engines(({{wiki:docs:ebay_307164541213_dataplay-optical-engine.pdf|eBay — DataPlay Optical Engine [Archive Listing]}})) ship from Italy. I have no doubts that the disks are functional if one has a working reader, but the optical engines are bare units with only an undocumented ZIF connector, so testing them would require some electronics engineering. I have yet to see a DataPlay player or pre-recorded disk eBay, so its safe to assume they're exceedingly rare, thus making this format difficult to interface with.
  
 +//Update:// The 21x disk packs (63x disks total) I received from this seller had moldy paper inserts. If you attempt to purchase these, be sure to have the seller send a photo before shipping.
