begin in the 1980s , Sony produced the Discman , a CD version of its democratic cassette Walkman player . I had a Sony Discman or two in the 1990s , and they were pretty slow — typically grapple - shape credit card player with a smattering of push button and a plaza to slap some AA batteries . Butthe Sony D-88 was different . It was a portable CD player that was too minute to fit a CD inwardly .

Yeah , let ’s back up a piffling .

Your typicalcompact disc(CD ) has a diam of 120 mm , or 4.72 inches . But there ’s also a much less commonMini CDformat , unremarkably sized at 80 millimeter ( 3.15 inches ) . These Mini CDs were sometimes used for compact disc bingle , or bundled with computer devices for their drivers , or as gimmicks at tradeshows . They ’re also the reason tray - based CD histrion have multiple circular cut - outs in the tray : The smaller discs can correspond in the center , and the spindle comes through the midriff and seize them . ( The spike cutting - out is the same sizing regardless of total CD diameter . )

Sony ’s D-88 Discman , introduce in 1988 , envisage a world in which the Mini CD might really be democratic , and that people would bear around a bunch of certificate of deposit singles . Sadly , this was never a world I inhabit , but it is a little riveting to reckon . What ’s far weirder is that the D-88 can act a full - size CD , with the spinning disc sticking out on two English , whirring away , ready to check into bits . What could possibly go wrong ? ! Here ’s an excellentTechmoan telecasting explaining the whole sight :

As the video reference near the death , Sony had done this kind of thing before with a Walkman too low for a tape ( my family had one ! You just popped it open to thrive it to regular size ) , and even a record player too low for an LP ( which was kind of awing , since at least it was n’t plan to go in your pocket ) .

Okay , let ’s get word it , commenters . Did anybody own one of these gadget ? If so , what CD ace were you listening to ?
