"Portability" which was an important element as a portable equipment was persisting pursued.

2. Longest in industry- A continuous reproduction of two of about 145 hours is achieved.
The longest in the industry because of making of an electric circuit by the optimization of the supply voltage to adoption of a highly effective motor, further development of LSI in a low voltage, and each IC etc. thorough a conserve electric power. - [It] continuous reproduces and about 145 hours of two are achieved. (The attached charge pond, [it] used together one Sony alkali AA dry battery, and the LP4 mode reproduced) The continuous reproduction time was postponed for about as many as 45 hours compared with our company MD Walkman “MZ-E900" (sale on September 10, 2000).

Efficient 音飛び(unknown word) guard mechanism “G-PROTECTION" which Sony developed is installed aiming at "音飛び(unknown word) 0". Jumping, and worry is hardly, and can enjoy music pleasantly as for sound even if keeping shaking while out for a long time because (*S) deals corresponding to shake and vibration in every case momentarily

6. DSP TYPE-R adoption for new development ATRAC
[It] corresponds to DSP TYPE-R for new development ATRAC installed in high spec MD deck of Sony and recording MD Walkman “MZ-R909" (sale schedule on August 21, 2001), etc.If the disk to which the SP stereo was recorded by “TYPE-R" is reproduced, abundant music “TYPE-R" original tone quality can be reproduced.
