Blue lasers offer three times the storage capacity of DVDs
Blue lasers have a shorter wavelength than traditionally used red lasers, allowing more data to be stored in smaller spaces. Two companies promoting blue laser technology at the RSNA meeting are presenting similar claims and products.
Blue lasers have a shorter wavelength than traditionally used red lasers, allowing more data to be stored in smaller spaces. Two companies promoting blue laser technology at the RSNA meeting are presenting similar claims and products.
Plasmon claims its ultradensity optical technology can store 30 GB on a single cartridge, three times the capacity of DVD and magneto-optical media. Sony claims it can pack 23 GB on a single-sided disc with a technology that boasts 11-MB/second-read and 9-MB/second-write speeds.
Sony has developed three models: an internal SCSI, an external SCSI, and an external USB 2.0 version. They read data at 11 MB/sec and write data at 9 MB/sec.
Both companies featured products based on blue laser technology in the context of plans to develop subsequent generations that might store beyond 100 GB on double-sided media. They expect this capacity within several years.
Plasmon plans to double storage capacity at least every 18 months, reaching 120 GB within three years. This continued development will make ultradensity optical technology ever more appealing.
Can MRI-Based AI Bolster Biopsy Decision-Making in PI-RADS 3 Cases?
December 9th 2024In patients with PI-RADS 3 lesion assessments, the combination of AI and prostate-specific antigen density (PSAD) level achieved a 78 percent sensitivity and 93 percent negative predictive value for clinically significant prostate cancer (csPCa), according to research presented at the Radiological Society of North American (RSNA) conference.
