These patents are several years old. Is there any evidence of any commercial application or attempted application for any of these patents?

due diligence alert -- patent doesn't mention erasability, write-once timing, or cost be very careful here; company press claims a "future" version to improve upon already-commercial consumer-writable disks, but this patent doesn't cover the necessary details to make a competitive evaluation. first, pick your level of interest: - erasability? (e.g. for computer data, VCR replacement applications) no mention in the patent; the claims cover write-once media only. check marketspeak against DVD-Forum progress. [DVD-RAM extended by blue laser, pit-depth modulation, etc. -- blue laser can give 3-4X, pit-depth 2-4X, so existing non-exotic media can yield >200GB per 120 cm disk.] perhaps the "super-FMD" RAM only mentioned in website PR (18-months away) has some horrible disadvantage, like having to slowly-read a whole sector/surface in toto for bulky, slow, re-writing. - ease of consumer-level write-once? [DVD-R is the current benchmark here. extensions include multifrequency readout.] perhaps you don't need more than serial access, which is good enough for camcorder apps...but how about disk cost, read mechanism size, etc. - only care about read ops? which applications will this enable that don't have a cheap answer? HDTV? hardly, already covered by straightforward extensions to DVD, per above but with erasability as a bonus. lots of cagey stuff here. "initial discussions" with major companies could mean one phone call with a courtesy answer. stock status involves bulletin board status with shell companies. no discernible mention in respected trade journals -- at a minimum, this would be headlined in e. e. times if something was amazing. there are plenty of storage schemes (holographic, OROM, magneto-optical, nonvolatile amorphous, ferromagnetic, bacterio-rhodopsin, dye ala p. rentzepis) out there for the choosing, some sponsored by huge trading combines, some put forth by small companies with tiny half-life.
