Press Releases Withdrawal from the Recording Media Business

On a computer, the one with the best record is linear digital tape, which is what banks and other people who need accurate access to old records use. They last a decade or two before they need to be backed up. Next comes a decent hard drive, but you need to (a) keep it exercised, and (b) transfer all the data on a drive to a new ones every few years. All digital information needs transferring to new media before the read errors become uncorrectable. I have a few floppy disks that are still readable after 35 years, but 90% of my old floppies are now unreadable even in the drive that made them, which works perfectly when checked with new floppies. For any digital format, you also need to maintain a system which can read the format both as bits and as files, as they tend to fall out of common use, and some proprietary file formats have been almost unrecoverable for thirty years or more now. In audio, I could mention the Sony units from as recently as 30 years ago that used a Betamax tape drive, producing recordings that are now beyond recovery due to tape aging, a proprietary file format, and a lack of spare heads for the players. Flash drives, either as thumb drives, SD cards or as Solid State Discs are too new for reliable figures to be available yet. For analogue longevity, the best we know of is a shellac 78rpm disc or a cylinder, stored in a cool, dark place. We know that can last at least a century, with some degradation of the stored signal, mostly caused by wear due to playback. Good quality vinyl is approaching 70 years now, and is holding up well so far. Magnetic tape lasts a few decades with a good binder formulation and correct storage, given regular rewinding to reduce print through from one layer to the next. The shortest archive life for digital storage is any optically writeable medium, with some only lasting months or even weeks before becoming unreadable. My personal record for that was a disc that was written on a Monday, checked out perfectly, and was unreadable by Friday. For really long term storage, write the notes to be played and words to be sung down using Indian ink on parchment, that is known to last for many centuries unless the vermin get to it. Papyrus falls apart after a couple of millennia even if kept dry and dark... -- Tciao for Now! John. Thanks for the response. It seems like it would be a good idea to supplement these local backups by backing up to a cloud service, where they have redundant disk arrays and periodically upgrade their storage media. Does anyone know which cloud storage service is supposed to be the most reliable and secure? |

Why do you think so many tapes, discs(optical and vinyl), and actual framed art are clogging up Goodwills, Salvation Armies, and other thrift-stores? Unrelated, but why do you see so many floor & table-lamps in those stores? Simple: Recessed lighting, less clutter. Society is migrating away from physical copies of everything. The internet is now robust enough, and storage cheap enough per TB(let alone GB!) that everyone is just copying everything old to digital, storing it in the cloud or on hard-drives, and buying or accessing newer releases on-line. Press a button on a remote, and the material appears on your TV. Or access it from your phone or a screen in the car dashboard. Or on the TV in your grandma's house or hotel!

Because people don't care about preserving these things. There's always more to be had. Unrelated, but why do you see so many floor & table-lamps in those stores? Simple: Recessed lighting, less clutter. I dunno. My eyes get worse as I get older and I need more direct light. Recessed lighting would be a waste for me. I THOUGHT my hearing was getting worse. At one time, I could detect elevated levels of tape hiss noise. However, even though I like them, I have to blame my ability not to hear that tape noise on my Philips headphones. p.s. For eyes (eyesight), especially "floaters", I'm trying 1000 mg Bilberry pills. Jack Society is migrating away from physical copies of everything. They haven't lived with that mentality for long enough yet to know whether they'd miss it or not if it disappeared. The sad truth is that they probably wouldn't. I'll have to admit that while I don't have any compelling need or desire to get rid of my record collection, I really don't spend much time with it any more. I'd hope that when the time comes to get rid of it, I can find someone who will appreciate it. I'd feel terrible to know that it's gone into a dump. I for one will NEVER relinquish my physical media for as long as I live. You just can't beat the quality of direct playback in your own home. I suppose that there's quality material "out there" that I could play back in my home with higher quality than playing an old record. The difference isn't with the quality of sound, it's with the quality of life. Also, the feeling of security that you know what you have, and what you don't have. -- For a good time, visit http://mikeriversaudio.wordpress.com |

LOL .... which you apparently have the ability to judge better that anybody else, on a less than average sound-quality pair of headphones. Wow. Hold on there, Bubba Geoff. As I see it, hear it and read it, everyone wishes to be a critic. I admittedly mentioned my Phillips headphones lacked in the higher frequency range, I discovered it myself, not by audiophile gear, but BY MY CHEAPO DELL COMPUTER SPEAKERS. But some say the headphones lack bass, but are fine in the remainder of man's hearing range. What gives? Who should I believe? And I THINK he (hip-hop music fan) was knocking me, and my, ahem, as he wrote, "mastering". Jack High quality is so easy to achieve if one's criteria is set sufficiently low. geoff |

Metal masters are nice to keep, but there are so few of them compared to the number of pressings. Metal masters aren't all that common (most are cut on lacquer), Which are then plated. If you keep the lacquers, the plasticizer from the lacquer outgasses and the lacquer layer shrinks and separates from the base. If you keep the metal, it can corrode (although cosmolene and the like can help a whole lot). Often test pressings will outlast both of them, but not always. and metal stamping parts tend to get discarded when they start making funky pressings (some funkier than others). You don't want the inverse stampers, you want the mothers the stampers are made from. Lots of folks at smaller labels didn't run 2-step process. All they have is one piece of metal. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Can you recover your data after the company goes into liquidation after selling all the hardware? There's nothing wrong with maintaining an on-line backup as plan B, but you need to have a plan A as well. You do, however, need to make sure that you can still access your on-line data, and that it still matches your local copy on a regular, fairly frequent basis. Eecently, I wanted to use Outlook on my new phone as well as on the new computer, so I bought Outlook for the PC and installed free Outlook on the phone as well. They won't talk to each other, even with a third party program. I have to use a third party calendar app on the phone. If you use the online version of Outlook, it is completely impossible to get a local copy of your data other than by printing the page off, so you can't use the programs without an internet connection. How long do you reckon Microsoft will keep giving you free storage space? How long before they drop support for this year's data format from the OS? They're already considering a subscription model for the operating system, so they will be able to turn your computer into a brick by clicking a mouse button. -- Tciao for Now! John. |
