Title: Optical information recording medium and method for recording data
Inventor: IIDA TAMOTSU
IPC: G11B7/2405
Filed: 2000-09-29
Abstract: PROBLEM TO BE SOLVED: To provide an optical information recording medium, which has excellent reproduction signal features at high density, and a data recording method for an optical information recording medium. SOLUTION: In an optical information recording medium, data is recorded at grooves and between grooves so that physical change of groove, which is shaped on a substrate, indicates a recording mark, and asymmetries of between-groove and groove reproduction signals are restricted within ±20% respectively. In a data recording method, two recording beams are applied to the optical information recording medium to form a groove. One of the recording beams is polarized perpendicular to the direction of travel by a pulse form driving signal to record at grooves and between grooves, which have a required recording mark and space. The recording mark is recorded in the direction that widens groove width by polarizing the recording beam outside.  On the other hand, the space having the same space length as the mark length of the recording mark is recorded in the direction that narrows groove width by polarizing the recording beam inside. At this point, polarization driving time width of the driving signal to polarize the recording beam inside of groove is set so as to be narrower than that to polarize the recording beam outside of groove.

Title: Plasma display panel
Inventor: YAMAMOTO HIDEAKI
IPC: H01J11/26
Filed: 2000-10-20
Abstract: PROBLEM TO BE SOLVED: To make a glass of a PDP difficult to be broken when dropped or hit. SOLUTION: With an aluminum plate 6 bonded to the rear surface of a glass substrate 2 on the rear surface side, its thickness is reduced (for example to 1.8 mm, being 65% of 2.8 mm), as being hard to deflect when dropped while a glass substrate 1 on the front surface side is made thicker for compensation (for example to 3.8 mm, being 65% of 2.8 mm), thus the present thickness of PDP being kept as a whole. Dielectrics layers 3 and 4 are formed by sintering a material whose linear expansion factor is close to the glass substrate, allowing no compression stress to remain on the glass substrate, nor tensile stress on the dielectrics layer, due to difference between expansion and contraction at sintering. The width A of a bonding part 5 is widened.  Thus, the deflection of the glass substrate 1 resulting from dropping is less, suppressing breakage of the glass substrate 1 due to cracking of the dielectrics layer 3. The strength against hitting on the front side is raised when the thickness of the glass substrate 1 is increased.
