Ultimate MD Jacket Size

"MD Jacket Size" refers to the dimensions of the blank MD disc case, defined by Sony as w72 x h8 x d80mm. Since its inception, MD, like a deity, has been an intangible concept—heard of but unseen.

However, Panasonic, known for its prowess in miniaturization, thought differently after a two-year hiatus. With their bold new offerings SJ-MJ5 and SJ-MJ7, measuring 72 x 80mm—just the right fit for the standard dimensions—they coined the term "Just MD Jacket Size". Though not ultra-slim at 16.9mm, they dominate the realm of pocket-sized devices.

Panasonic Electric claims the MJ7, developed with "the collective technological prowess of the entire company," features a magnesium alloy (possibly only on the cover) that's 2.4 times harder than aluminum. The silver-white body with its subtly detailed window reflects the disc's color, while the MJ7S's finely concentric circular hairline finish echoes the technological imagery of the disc*. This high-precision Circular processing technology applies a spiral gloss in micrometer units on the body cover. Due to oxidation upon contact with air, Panasonic states that approximately one year was spent developing new materials and surface treatments to achieve this exquisite design, ultimately merging technology with material to achieve the ultimate sense of science and technology. The simple, textured, and atmospheric design craftsmanship also made the MJ7 a dazzling superstar of its time.

Not only groundbreaking black technology but also infinite combat power, Panasonic pursues every new aspect from inside out. It matches its Upward Remote Control with avant-garde upward-angle backlight LCD, featuring a user-friendly design for both outdoor and home use without needing to flip the display for confirmation. The controls evoke a miniature control center in the palm, embodying Panasonic's consistent product image of bold and advanced near-futurism. However, the shock resistance seems to lag behind with a somewhat primitive 10-second protection...

The new "Quick Fit Earphones" feature a new diaphragm shape and rounded earpiece design, promising both thinness and comfort in wear, delivering comprehensive high-quality sound from bass to treble.

The rechargeable battery offers a moderate 6hrs performance, with combined usage achieving up to 15hrs of endurance.

*Sony's flagship portable audio often utilize magnesium alloy with hairline texture processing. Over the years, there have been recurring material defects such as oxidation and discoloration issues with the body (seen in models like MZ-E900, MZ-N10), yet Sony has never implemented a specific solution.
