MPO Tests of Sony MDS-JB920 Loading Mechanism

Here are some results of the test we conducted on this new SONY deck (MDS-JB920). Our process engineers bought following brands:

  • 100 pcs MAXELL
  • 100 pcs TDK
  • 50 pcs SONY COLOUR
  • 50 pcs SONY ES
  • 100 pcs Hi-SPACE
We noticed the following failure rates:
  • MAXELL 34%
  • TDK 44%
  • SONY COLOUR 57%
  • SONY ES 46%
  • Hi-SPACE 51%
Failures are coming from the following causes:
  • The Minidisc loading tray of the player is slightly too narrow and it scratches the MD shell and/or does not place the TOC at the right position over the laser. Result: TOC is not read properly.
  • Some of the MiniDisc shells are slightly too large. Result: new scratches, new errors.
MPO Point of View :
  • Our shell moulder will propose to us a new adaptation of the current mould to correct these troubles on Hi-SPACE discs (within 6 weeks).
  • Create a new shell design (100% new will come by Autumn 1999) to avoid these kind of problems.
  • For the current users of the MDS-JB920, insert the discs slowly (anyway, MD is not as solid as a VCR, so take care when inserting discs on any model).
  • For future customers of the MDS-JB920, please wait for a correction to be made to the deck.
Many thanks for all your comments on the discs, which helps us to progress !!!
