Misconceptions

In this section, we hope to address several popular misconceptions about MiniDisc. These are things we have heard across the internet in comments, videos, forum and social media posts, and beyond. Many are based on truth but are exaggerated or misunderstood.

This is the biggest misconception, and it is very subjective and region-specific. In Japan, MD was a successful and ubiquitous format - this is why equipment and discs are much less expensive in Japan. In Europe, MD saw moderate success while the US was one of the weakest markets.

Sony surely would have liked for MD to be as successful outside of Japan as it was domestically, but could adapt thanks to the CD Walkman (Discman) which was popular worldwide. See our Why MD FAQ for more.

Between 1992 and 2003 (if not later), MD was the best way to experience music on the go or to create your own mixes. Equipment, discs, and accessories were available in all major markets for those who wanted a format more flexible and convenient than CDs or cassettes, and those who used MD often sang its praises.

MD equipment was produced for 20 years and blank media for more than 30 - compare that to HD-DVD which was discontinued in less than 2 years, or MD's rival DCC which lasted for 4 years.

This one is true, but mostly irrelevant.

Record labels were alarmed by the high quality of MD recording and feared bootleg copies of albums would harm their sales. To counter this and threats from US legislators, MD has a copy protection system called "SCMS" - the Serial Copying Management System. This protection system has no impact on normal use of MD as a music format.

When you record a track from a digital source, such as TOSlink or coaxial SPDIF, it is "flagged" with SCMS and attempting to record *from* that track to another MD recorder will be blocked. This means you cannot record an MD from a CD, then have others make their own copies from your MD.

This protection system has several loopholes. First, it does not affect analog audio such as RCA or 3.5mm at all. You can make as many copies as you like over standard analog audio and it cannot be blocked. Second, it was not implemented on a lot of professional-class equipment such as the Sony MDS-Exx PRO decks. Finally, it is mostly irrelevant today because there is almost no need to create a 2nd or 3rd generation copy of audio from a MD. Instead, record each disc from the original source such as the CD. This also prevents recompressing the audio.

The SonicStage software for NetMD introduced its own DRM with the "check-in/check-out" system for tracks copied to MD, but there is little reason to use SonicStage nowadays and the new software does not have the same annoyances.

It was, and Sony held most of the patents (Philips held some too, but developed the rival DCC format instead) but Sony licensed MD to numerous competing manufacturers. Some, such as Sharp and Panasonic, even made their own mechanisms and implementations of the ATRAC codec.

MD was less open than cassettes or CDs, but open enough to have over 2200 unique devices made by at least 34 different brands.

MD does indeed use lossy compressed audio rather than the uncompressed audio on a CD. However the scale of the difference has been exaggerated.

MiniDiscs use a compression format called ATRAC at 292kbps. Sony had the engineering resources to not only create an efficient audio codec, but also to build dedicated chips to encode and decode this codec. This resulted in audio compression that was nearly transparent (impossible to notice compared to the original CD) while using much less data. The earliest iterations of ATRAC did have more noticable compression than later encoders - use a recorder made after 2000 for the best recording quality, even when played back on older devices.

The LP2 and LP4 recording modes, introduced in 2001, did reduce audio quality by halving or quartering the bitrate allocated to each track. This decrease was offset slightly by the use of a newer codec called ATRAC3. ATRAC3 should not be confused with the third iteration of the original ATRAC, and is incompatible with older MD equipment. LP2 mode can be compared to an average MP3 file in quality (128-192kbps) while LP4 is typically too compressed for music but is great for podcasts and audiobooks.

In short, MD uses high-quality lossy compression similar to that used on streaming or downloading services. It is not an archival format but a listening one with much better audio fidelity than cassette tapes.

Also presenting as "NetMD needs NetMD discs" but just as incorrect. MDLP does not need special discs, and no such discs were made. A major selling point of MDLP was that it can store 2-4x the audio on regular MiniDiscs.

You can also mix and match SP, LP2, and LP4 tracks on a single disc. If played on a SP-only machine, the LP tracks will only play silence. Many will also show "LP: " on the display before the track title to let you know that it's an LP track.

Hi-MD, released in 2004, does have its own upgraded 1GB discs that are not at all compatible with older MD equipment. These discs are easy to spot and much more expensive than standard MDs. Hi-MD could also format standard MDs into a Hi-MD format that will not play on other machines. Hi-MD is much more expensive and rare so the risk of encountering this is low.

MD is a digital format, so this is completely untrue. Whether recorded from an analog or a digital source, MD will encode the audio as an ATRAC file stored on the disc. This is digital data, 1s and 0s, so the disc itself does not make a difference so long as it isn't malfunctioning.

There does not seem to be much difference in reliability between different brands of discs, so buy based on the designs and price you like.

SonicStage is the clunky software used with NetMD in the early 2000s. It had annoying DRM and bizarre shortcomings that made it less than ideal for managing your MDs. It also no longer connects to NetMD devices on modern PCs without a custom driver and disabling Windows security features.

Luckily, the NetMD protocol for connecting MD recorders to PCs has been reverse-engineered and new software has been created to make SonicStage unneeded and redundant. The most popular of these is Web MiniDisc Pro, developed by asivery (and others) and hosted by the wiki. This is a website that connects to your NetMD recorder and copies tracks faster, with better quality, and with less restrictions than SonicStage did. Because of Web MiniDisc Pro, NetMD recorders are very desirable and convenient for copying music to MDs.

Only true with a single MD model: the Sony MZ-RH1. This has made that model very desirable and expensive.

Otherwise, this misconception may come from the awkward "check-in" DRM system that SonicStage used. When you copied an audio file to MD via SonicStage, it would be marked as "checked-out" in your library, and you could only "check-out" a file so many times before you would be blocked from copying it to any more discs. To check a track back in, you would connect the MD to SonicStage and remove it from the disc. This also causes some recorders to refuse to delete a track, showing a "track protect" message so that you could not lose the ability to "check-in" the track later.

Thankfully, all of these inconveniences are gone with modern NetMD software like Web MiniDisc Pro - it can write and erase discs with no SonicStage limitations and it can copy ATRAC audio from MD to a PC on a number of NetMD portables.

Web MiniDisc Pro uses WebUSB to connect to your NetMD recorder from within the browser window. As of early 2025, only Chromium-based browsers such as Chrome support this feature. But you don't need to use Google Chrome itself - other browsers based on Chromium such as Brave, Edge, and degoogled-chromium work fine with Web MiniDisc. Note that Vivaldi is Chromium-based but has issues with WebUSB - check the Web MiniDisc Pro app for details.

There is also a standalone version of Web MiniDisc Pro called ElectronWMD. This uses the Electron platform to bundle the Chromium components without the rest of the browser, and is used on apps such as Visual Studio Code, Discord, and Spotify.
