Indicates if it's possible to record MP3s with the MD player.

The playing time indicates how long the batteries will last during continuous playing.

Minidisc "Long Play". A encoding method for audio on Minidisc that offers two modes: one gives 160 minutes stereo ("LP2"), the second gives 320 minutes stereo ("LP4"). LP2 is stereo encoded (each channel is independent), LP4 is joint-stereo (both channels are coded simultaneously).

Shows if there is a radio in-built.

An essential feature for those of you who enjoy plenty of bass.

An AC adapter is necessary if you wish to power your player directly from a wall socket. This is a useful feature if you wish to save your batteries for when you're roaming.

The long-term cost is lower with good rechargeable batteries. This option avoids the expense of having to regularly buy AAA batteries, the non-rechargeable standard.

The remote control means that you can control the player without having to take the unit from your pocket or belt.

Specifies whether your MD-player can record from other audio sources (such as CD players, cassette decks etc).

ATRAC (Adaptive TRansform Acoustic Coding) divides the 16 bit 44.1 KHz digital signal into 52 sub-bands in the frequency domain (after a Fast Fourier Transform). The sub-bands in the low frequencies are finer than the ones in the high frequency range. A psycho-acoustic transfer function that takes advantage of the masking effect and the absolute hearing threshold then removes enough information to reduce the data stream to 1/5th of the original size. Each channel receives that treatment separately (the Sony MZ-1 portable MD recorder features one ATRAC encoder/decoder chip per channel). PASC (Precision Adaptive Sub-band Coding -- used in Philips now defunct DCC [Digital Compact Cassette]) divides the digital signal into equally spaced sub-bands and removes less information (to only 1/4th of the original size). PASC is essentially the MPEG Layer 1 audio standard (can be decompressed with MPEG Layer 1 players after a trivial preprocessing step).
