Remarks

• Predecessor model: Sony MDS-JE 530
• Successor model: none in the 600 series. Sony MDS-JE 770
• Compared to the predecessor model JE 530, the JE 640 was 100 to 150 DM more expensive.
• The new compression ATRAC 3 had nothing to do with the previous ATRAC designations. This compression made it possible to achieve twice the recording time (LP2) or twice the recording time (LP4) on conventional MD. The devices of the whole series were downward compatible and could also record and play back in classic ATRAC systems. On the other hand, older MD decks could not play ATRAC 3.
