Here Comes Optical Tape ... Again.MARK: Hal, I've just heard some wonderful news. There's a new version of optical tape in development. HAL: You know I'm a big fan of "Buffy, the Vampire Slayer," but I never expected optical tape to come back from the dead. MARK: Don't drive a stake through its heart until you hear what it's about. A startup called MicroContinuum, in Cambridge, Mass., is working on it. Most of the people involved are ex-Polaroid, who stayed with optical tape after Polaroid pulled out of a consortium with Avid, Lucent, and LOTS Technology. HAL: Too many cooks.... MARK: I know. But apparently, the cooking is almost done, and the broth broth liquid media for culturing microorganisms. cooked meat broth a medium useful for culturing anaerobic bacteria. enrichment broth one modified to permit growth by selected bacteria. may be ready to serve up this year. They say they're in the "commercialization" phase. HAL: That's the toughest one, though, isn't it? Everybody who's tried to bring out products based on new storage technologies has been 'way under-funded. MARK: MicroContinuum's money is coming from industrial and government contracts. HAL: They'll need to reach into deep pockets, all right. I remember the optical tape system that came out ten years ago, from a Canadian company called Creo. The drive cost a couple of hundred thousand dollars--in 1990 dollars--and they wound up giving them away to the Canadian government for accumulating data from seismic explorations. How much does MicroContinuum expect to charge for their recorder, and where do they say the customers are? MARK: Back in 1990 when Creo and Imperial Chemical--which made the media--were putting that system together, there was only one application that could accept hundreds of gigabytes of streaming data Data that is structured and processed in a continuous flow, such as digital audio and video. See streaming audio and streaming video. , and that was remote telemetry telemetry Highly automated communications process by which data are collected from instruments located at remote or inaccessible points and transmitted to receiving equipment for measurement, monitoring, display, and recording. . But things are different now. I don't have to tell you about the data explosion. I'll bet I'll Bet was an NBC game show that aired from March 29 1965 to September 24 1965, that was created by Ralph Andrews. The host of this program was Jack Narz. It was a precursor of It's Your Bet, which aired with four different hosts during its four year run: Hal March, Tom there are a hundred companies whose commercial databases are larger today than the Canadian government's seismic database was a decade ago. And that's not counting all of the folks who are talking about streaming audio A one-way audio transmission over a data network. It is widely used on the Web as well as company networks to play audio clips and Internet radio. Computers in home networks stream audio (mostly music) to digital media hubs connected to home theaters. and streaming video A one-way video transmission over a data network. It is widely used on the Web as well as company networks to play video clips and video broadcasts. Computers in home networks stream video to digital media hubs connected to a home theater. from servers. HAL: I'll grant you that demand has exploded exponentially. But to meet that demand you still have to be cost-effective. MARK: They seem to have covered that base too. A DLT (Digital Linear Tape) A magnetic tape technology originally developed by Digital for its VAX line. The technology was later sold to Quantum, which makes it available to other manufacturers. DLT uses half-inch, single-hub cartridges similar to IBM's 3480/3490/3590 line. library that can hold 6.8TB on 170 cartridges costs about $600,000. MicroContinuum is developing 1TB cartridges and a seven cartridge library. And their target price for the equivalent in storage capacity is almost an order of magnitude A change in quantity or volume as measured by the decimal point. For example, from tens to hundreds is one order of magnitude. Tens to thousands is two orders of magnitude; tens to millions is three orders of magnitude, etc. lower: fully populated A circuit board whose sockets are completely filled with chips. , you'd have 7TB for just $70,000. HAL: I have to admit: that's impressive. MARK: So, now take a quick trip down memory lane: What was the format of that Creo system? HAL: It had a reel-to-reel transport; the tape was one inch wide, and it was write-once only. MARK: Hold onto your seat: MicroContinuum is talking about rewritability. HAL: In addition to write-once, or instead? MARK: They say they'll offer both. They anticipate media manufacturing will begin in the second half of this year. HAL: What's the underlying recording technology? It must be phase-change. MARK: Right. And actually, they have three core technologies altogether. Phase-change materials, of course, for the recording layers. Something they call "advanced surface microforming," which is supposed to be in their second-generation product-- HAL: Ooop! They're talking about the next generation before they've even built the first? MARK: They're talking three generations ahead! HAL: Uh oh. MARK: The third breakthrough is called "linear variable data microforming." It apparently optimizes optical tape for a variety of recording applications, including prerecorded pre·re·cord tr.v. pre·re·cord·ed, pre·re·cord·ing, pre·re·cords To record (a television program, for example) at an earlier time for later presentation or use. Adj. 1. media, home-recording, and digital-projection cinema. HAL: And when, pray tell, is THAT supposed to happen? MARK: They don't say, and I have to agree with your skepticism there: it probably won't be very soon. A few years, at least. HAL: A wise analyst once advised me: "Don't invest in anything that requires three miracles." I think I'll wait to recommend optical tape until they've commercialized at least one of them. MARK: Okay. But do this first: extrapolate extrapolate - extrapolation future products from current technologies, and tell me what other storage system would be able to compete with optical tape a few years down the road? HAL: That's a good point. Unless there's a huge breakthrough in 12-inch optical disks--which I doubt--there won't be anything that big on the market, and certainly not in that price-range. But let me ask you a question: If they want their optical tape library to serve the streaming-data marketplace, what kind of transfer rates are they projecting? MARK: I don't have that info, and I suspect that it's not something they can predict solely from their laboratory benches. Their first beta products are supposed to arrive in six months. HAL: So let's revisit re·vis·it tr.v. re·vis·it·ed, re·vis·it·ing, re·vis·its To visit again. n. A second or repeated visit. re this topic toward the end of the year. Okay? MARK: Fine.
