Recorded tapes

It seems to the author admirably demonstrated in a recent article by Camras´ that economy is no longer a primary problem with standard tape. How it is time for someone to get rid of the one remaining bogey: hiss. Even the 7-1/2-ips tapes played with a 90-microinch head exhibit altogether too high a hiss level, and the published data on the CBS system doesn´t promise much. Surely some of this astronomical packing density obtained by Goldmark, Mee, Goodell, Guckenburg, Rrophy, et al., could be traded for greatly improved signal-to-noise ratio. I know there are a number like me who would nelcome a high-quality, compatible cartridge. I only hope it isn´t too late to avoid another ´War of the Speeds.´
