Highly sensitive magnetic layer that provides not only a high C/N ratio of
46dB and a wide power margin but also outstanding stability, sufficiently
durable to withstand more than one million record/erase cycles
Groove that is 1/1,000 mm in width and 7/100,000 mm in depth is created
with ultra-high precision and a track pitch of 1.6 µm. This results in an
extremely low error rate over the entire disc
High-precision cartridge with outstanding rigidity and heat resistance
ensures stable disc rotation
Moreover, the lower shell of the cartridge uses ultra-sonic welding to
ensure excellent shock resistance, including resistance to warping type
distortion
