ソニー「オーディオカセット/ES・I ES・II」カタログ・平成2年10月

Six-page brochure for the SONY ES cassette line - ES-I (Normal Position, Type I) and ES-II (High Position, Type II). The central theme is vibration control: Sony explains how cassette deck transport and external sources generate two types of vibration that degrade sound quality, and how the ES mechanism (Establiss Mechanism) counters both. Interior spreads detail the engineering - vibration absorption and vibration minimization through the ES chassis construction. The back page has the full price list for both ES-I and ES-II from 46 to 100 minutes, plus complete specifications including frequency response and noise figures.
