Panasonic SJ-MR100

Offered in SJ-MR100-S (silver) and SJ-MR100-K (black)

Features: Smallest and lightest MD recorder as of June, 1999. Unit incorporates .25um rule LSI and newly developed one beam optical pickup (world's thinnest: 6.6mm). Text display on main body is 2 X 12 characters. Edge mounted jog dial with integral push button for labelling and track selection (while playing a track, other track names may be examined and a new track selected). Can title while playing a track (though machine updates TOC and leaves unit at start of disc after every track title operation). Special “one track record” function puts unit into rec-pause mode after a CD track finishes. Divide rehearsal mode with 60ms adjustment step (like the Aiwa AM-F70 and home decks). Backlit remote. 40 second shock memory. Synchro-recording, sampling rate converter. Time Mark mode (automatic track marks at 3 or 5 minute intervals). Battery charges only when unit is stopped. No AGC(?), recording level control limited to “high/low” sensitivity switch (manual states that High sensitivity is for recording from portable products, and Low sensitivity is for recording from hi-fi products or boomboxes).

Continuous CD

• 1st track recording function When the recording of the 1st track on the CD is finished, it automatically enters the recording standby state, and when the CD is replaced and the 1st track is played again, the recording starts automatically. This is convenient when recording the first tracks of several CDs on one MD continuously.
• “40-second memory anti-vibration function” to protect sound from shocks
• Katakana character input support
• Battery level display function
• Equipped with optical digital input terminal
