TL;DR: In this paper, the authors developed a new error correction method (Picket: a combination of a long distance code (LDC) and a burst indicator subcode (BIS)), a new channel modulation scheme (17PP, or (1, 7) RLL parity preserve (PP)-prohibit repeated minimum transition runlength (RMTR) in full), and a new address format (zoned constant angular velocity (ZCAV) with headers and wobble, and practically constant linear density) for a digital video recording system (DVR) using a phase change disc
Patent
Method and apparatus for modulating and demodulating data into a variable length code and a providing medium for implementing the method
TL;DR: A SYNC bit inserting section 14 adds a sync signal to a train of codes, after adding a minimum run, said sync signal having a pattern that breaks a maximum run.

TL;DR: Recently, a storage capacity of 9 to 10 GB on a 12 cm optical disc was demonstrated using a red laser (650 nm) and a dual-lens objective with a numerical aperture of 0.85 in combination with a thin transparent cover layer.
Patent
Color liquid crystal display device
Shuichi Haga,Tatsuhiko Matsumoto,Tsuneo Kusunoki,Takahiro Igarashi,Yoshihide Shimpuku,Takehiro Nakatsue +5 more
TL;DR: In this article, a color liquid crystal display device capable of displaying a large color gamut is provided, where a color filter is made of color filters of three primary colors that select the wavelength to transmit red light, green light and blue light.
Patent
Modulating method and demodulating method as well as modulating apparatus and demodulating apparatus
TL;DR: In this paper, a modulating method and apparatus and a demodulating method for a variable length code (d, k;m, n;r) which can provide a greater minimum reversal distance to allow recording of a higher density than ever is provided.
