I guess I don't know much about this company - is this line shocking because they are such a prominent player, or is this line more of a "We really didn't do much in this area thus nothing will really change"?
For example, I read that Sony once had good discs, but today are just re-branding discs of a much lower-quality brand.
I think this is of historical significance: it's a sea-change moment, with a leading manufacturer essentially conceding that optical media is no longer relevant and can never catch up, destined to fade into the past.
Those of us of a certain vintage will remember a similar thing happening to floppy disks - and there are lessons to be learnt from that. Grab a few of these and carefully hang onto them, in the dark and away from heat sources - while you'll still be able to get them in a decade's time, it'll probably be impossible to find any new good-quality media then: so on the basis that you might want one when you least expect it, have a couple handy just in case.
There's a certain melancholy here, having seen this technology through its entire lifecycle - but at least we don't have to worry about scratching USB mass storage devices. I think I have only one PC which still has an optical drive, and it's the one which still has a floppy drive.
Maybe we'll replace spinning rust, and flash memory, too, in time.

But the era of optical disc recording is gone, so it's a good decision to close blink disc business from business view.
For normal people like me, just have a felling that another era is gone, like the floppy disk, PCI sound card, dial-up modem, CRT monitor, film camera and so on.
