Uploading Topics (these are direct answers from Sony)

• High speed MD to PC uploading can be performed with recordings made from mic, line & optical sources.
• All Hi-MD formats that can be recorded with the units themselves can be uploaded (i.e. PCM, Hi-SP & Hi-LP).
• Uploaded tracks can [currently] only be played back on the PC by using the supplied SonicStage2 ("SS2") software.
• Extended SonicStage software will become available that will be able to burn audio-CD's.
• Exporting from Extended-SS2 to WAV is still unknown.
• Exporting from Extended-SS2 to MP3 will not be possible (an external WAV->MP3 step is necessary).
• The Macintosh is still not supported (even Hi-MD's "USB data storage" mode is reportedly not Macintosh compatible).

Tests with Prototypes of MZ-NH1 and Hi-MD formatted 74 min discs

• The speed of a Hi-SP download to MD is 8x (timed).
• The usable disc space on a 74 min disc formatted as a Hi-MD medium is 270MB; extrapolated to an 80 min disc this becomes 290MB (305MB unformatted).
• The transfer rate of a data-mode file copy (200MB video file) to MD (i.e. download) is 3.55 Mbps (Sony datasheet says 4.37 Mbps)
• The transfer rate of a data-mode file copy (same 200MB video file) from MD to PC (i.e. upload) is 6.22 Mbps (Sony datasheet says 4.37 Mbps)
• We did not succeed in ripping CD-audio in PCM format and transferring it directly to MD. Ripping CD-audio in PCM to hard disc is possible, but before transferring it it is converted to ATRAC (possibly to protect CD-audio from lossless copying).
• When playing back tracks that are on a Hi-MD formatted disc, the sound is also transferred back to the PC via the USB bus and will be heard over the speakers/headphones. (Contrast this to existing NetMD units where the sound is only available via the Walkman's headphone output).
• While playing back MD tracks over the PC it is possible to simultaniously record them with e.g. Cooledit 2000 (effectively a realtime upload).
• Using the SS2 program makes the MD inaccessible as a data-drive, so no simultaneous data/music transfers are possible.
• The uploading of existing ("NetMD") recordings (SP, LP2 & LP4) is not possible (tested with an MD recording made with our own MZ-N10, and with recordings made with the MZ-NH1 in "NetMD"-mode).
• Hi-SP files are stored on the disc as real Hi-SP audio (no half-baked LP2 to semi-SP kludge as with NetMD).
• All recorded audio is placed in a collection of ".hma" files (of unknown format) in a single directory on the MD. One large .hma file contains all the audio-data, the other files are for index-data & titles. These ".hma" files can be freely copied back to the PC hard drive, but no subsequent playback of them is possible. (They present fertile ground for further investigation however).

Etcetera (answered by Sony)

• A free official update from SS1.5 to 2.0 will be available in April.
• The battery cannot be charged via the USB bus.
• The Hi-MD equipment shown to date can record in either NetMD (aka "std-MD") mode to std-MD media or in Hi-MD mode to Hi-MD media, both via USB downloading as well as via audio inputs. So it's fully backward compatible with old equipment. Also SP & SP-mono recordings can be made from analog, mic & optical inputs.
• There is no PCM mono or Hi-SP mono mode.
• Track, album & artist title information is transferred separately to the disc and can be viewed separately on your display.
• Prices of units (Holland):
  • MZ-NH1: 479 €
  • MZ-NHF800: 399 €
  • MZ-NH900: 385 €
  • MZ-NH700: 299 €
  • MZ-NH600: 249 €
• The MZ-NH1's LiIon battery is removable just like e.g. a NH-14WM.

Comments on Hi-MD Gear Look and Feel

• The single-line display on the MZ-NH1 is a pity. One team member liked the MZ-NH900 more because of this. For people who don't use the remote much the single-line display does not give much info.
• The new LiIon battery of the MZ-NH1 can easily be put in the wrong way (flipped either vertically or horizontally). Initially one of the units we tried wouldn't work away from the cradle and we found it had indeed had its battery inserted incorrectly. Having both contacts on the bottom of the battery restricts it to having one orientation that will work out of a possible 4 ways that it can be inserted (contrast this with the NH14-WM where you get 2 working orientiations out of 4).
• The remote of the MZ-NH1 also works on the MZ-N10 but only shows text on the middle line of the display. Conversely, the MZ-NH1 works with old (NetMD) remotes.
• The MZ-NH1 clicks firmly into place in the docking station. You have to use the nicely placed release button to get it free (it cannot be accidentally released, as is possible with the MZ-N10's dock).
• In the menu you can choose between a "basic" and an "advanced" menu. We're not sure what that means, but perhaps for rookies the basic menu keeps operation simple. Maybe the final menu is so big that for easy operation only the frequently-used functions are in the basic menu.
• It was a little noisy at Sony so we don't know exactly how much noise the MZ-NH1 made. What we do remember is that we had to look at the flashing "REC" led to see if it was ready. So we don't expect it will be terribly noisy.
• We had the feeling than the MZ-NH1 was a bit heavy and did not have the same colour as the MZ-N10. Later, upon seeing an old MZ-E25, we felt it had about the same color as the MZ-NH1. That leads us to believe that the prototypes where of aluminium instead of magnesium (probably because aluminium is easier to use for prototypes).
• At Sony it was much too noisy to give the HD digital amp a good auditition.
• The MZ-NH1 is thinner that the MZ-N10. Because the MZ-N10 has a big bump to accomodate its display, the thickness of the MZ-N10 varies a lot between the display and the edges. The MZ-NH1 does not have such extremes of thickness and is in between the thickness of the MZ-N10 at its display and at its edge.

  Comments from another team member:

• The MZ-NH1 itself feels a bit less sturdy than other units like the MZ-N1, partly because it is thinner, but especially because the shell is easy to damage. The cradle is, however, the best I have ever used. It has a nice click-system, looks great, and all connections are now accessible during playback (which is now possible from the unit over the PC-speakers, because data can go both ways through the USB-cable of Hi-MD gear).
• (In response to a question:) The unit's noises during operation do not seem different than previous MD gear, but I have to admit that I was not really paying attention to this. The "data-save" that is needed after recording in order to write the data in active memory to the disc is a bit faster than before. The seek times are the same, though it seems that in higher bit-rate recording modes (like in PCM RAW-audio), the disc spins a little longer before the actual "seeking" starts. This must be due to the extra data that has to be processed per second.
• Furthermore, the other Hi-MD-units feel almost exactly like the equivalents in the MZ-R5xx range. The casings are mostly plastic, or partly magnesium. The designs of the remotes seem to be a bit more clumsy. Subjectively: I hope SONY will hurry to update the design of the MZ-NH1, because I prefer the design of the MZ-N1 and MZ-N10 above that of the MZ-NH1.
