Sony set to launch double density CD

(IDG) -- Sony is boosting CD storage capacity. Next month the company plans to launch a new type of CD that can hold twice as much data as the current format, Sony announced Wednesday.

The Double Density CD format allows up to 1.3GB of data to be stored on a disc, although the new system is not compatible with the existing CD format.

Sony will begin selling drives and discs to support write-once and rewritable versions of the Double Density format in North America, Europe, and Japan in April, a company official says. The first DD-R/RW drive from Sony has an ATAPI interface and supports 12X maximum write for DD-R/CD-R, 8X write for DD-RW/CD-RW, and 32X maximum read speed for all types of CDs, it says in a statement.

The new format is likely to face heavy competition from a variety of formats already battling for dominance in a fierce marketplace. The new system costs $249 for the drive and $1.99 and $2.99 respectively for the DD-R and DD-RW media.

To double the capacity, Sony made some modifications to the current CD format, of which it was one of the original developers. The modifications included a smaller track pitch and minimum track length, a change in the error correction system, and an expanded address format. The new format also includes a copyright control system to prevent illegal copying of data on the discs.

Comparable CD-RW drives are cheaper and CD-RW media currently sells in Tokyo's Akihabara electronics district for around $0.75 per disc, although the company is hoping the extra capacity will be enough to win over users.

Not so for some other formats that are closer in data capacity to DD-CD. Drives for Iomega's Jaz format, which offers 2GB of capacity per disk, cost around the same as Sony's new DD-CD drive. The new discs are much cheaper than the average $70 a Jaz disk currently commands. The DD-CD drive is also cheaper than drives for the 1.3GB version of MO (Magneto Optical), a rewritable optical disk format popular in Japan, and the bevy of DVD-based formats currently on the market.

CD drive makers will be watching, with interest, how consumers accept the new technology. Adding DD-CD support to existing CD drives can be done with minimal effort compared with switching to other unrelated technologies.

Sony first announced development of the format in mid-2000 when it said that development, jointly undertaken with Koninklijke Philips Electronics, was nearing completion.
