You are buying one or more sealed-new Sony EDM-650B 5.25" 650MB magneto-optical (MO) removable disk cartridges.
IMHO magnetic-optical (MO) disks are one of the best archival storage media ever developed. Some types of MO disks (WORM) can be written just once and are meant to be used for long-term storage of data that must be guaranteed never to have been altered. But re-writable disks like this one can be re-recorded over and over and can store large amounts of data for a very long time.
This listing is for sealed-new re-writable 5.25" 650MB MO disk cartridges made in Japan by Sony. This capacity is a good choice for long-term backup of data and programs from vintage Macs and PC's because the cartridges are less expensive than higher capacity disks and the recording technology is more conservative, hence even better suited to archives.Note that although 650MB MO disks can be read by almost all 5.25" MO drives, they cannot be written by recent drives such as Sony's RMO-S561 9.1 GB drive. Please confirm that your drive is fully compatible with 650MB MO disks.
Please see my other listings for other hard-to-find vintage drives and media.I have been collecting and restoring vintage computers for a long time. Please see my other sales forvintage Macs andMac parts, plus occasional other vintage computing items.
TERMS & CONDITIONS
I don't have a lot of silly rules for buyers: Pay for your item and I'll send it you. I've been a buyer and a seller on for more than 25years and have a near perfect response record. I'll trust you and you can trust me to do right.
Please use the shipping calculator to figure your shipping cost inside the US.
Why don't I offer free shipping? There's no such thing as "free" shipping. Sellers have to recover the cost of shipping. When "free" shipping is offered the seller has buried the average cost of shipping the item in the price. This means that buyers who are far away and would have to pay more for shipping get a discount while buyers who are close to the seller and would pay less are overcharged. This is especially true for large or heavy items. I don't think that is fair, so I don't offer "free" shipping.
Sorry, but due to fluctuating tariffs and uncertain US export/import rules I have temporarily suspended shipping outside the USA. When sanity returns I will resume sales outside the US.
