Features: "Jacket Size" MD Walkmans, world's smallest size and weight for a recording portable (as of Aug 24 1999), longest recording and playback times (as of Aug 24 1999), smaller size achieved through redesign of the optical pickup mechanism (MZ-R90/91's pickup is 50% smaller in frontal area than that of previous model MZ-R55), "One Touch Eject" feature, "Name Bank" function (allows you to store up to 600 characters worth of commonly used words in the unit for easy MD titling), "Smart Stick Controller" with titling and editing functions, "Joint Text" feature records the titles from a CD while recording (not achievable with all CD players), digital recording level control, 40 second shock memory, Synchro Recording from digital source. Headphone and line out are combined into a single plug (switchable between the two functions with a jog lever). No microphone sensitivity setting. MZ-R90 only uses high stiffness magnesium alloy for top of case.

Mis-features: Longish start from power-off state (ca. ~9 seconds) and track seek times (ca. ~2-5 seconds) due to slow [power saving] drive motor spin-up gives unit a sluggish feeling response to user input.



Specs: Sampling rate converter converts to 44.1kHz from 48kHz/44.1kHz/ 32kHz sources, frequency response: 20-20,000Hz +/-3dB, max output level: 5mW+5mW, AC100V.
