OPTICAL TAPE WITH AN INCREASED TRACK PITCH FOR IMPROVEMENT OF TRACKING PERFORMANCE AFTER SEAM
In at least one embodiment, an optical data storage tape is provided. The optical data storage tape includes a read/write data area including a plurality of writeable tracks for storing data thereon, each writeable track having a first track width. The optical data storage tape further includes a seam area positioned proximate to the read/write data area. The seam area including a plurality of non-writeable tracks, each non-writeable track including a second track width that is greater than the first track width for each writeable track.

Optical information recording medium having first and second pit row of identical reflectance
In a case where (i) a reflectance calculated from a reflected light amount obtained from a longest pit (P1max) or a longest space (S1max) in a first pit row is defined as a first reflectance and (ii) a reflectance calculated from a reflected light amount obtained from a longest pit (P2max) or a longest space (S2max) in the second pit row is defined as a second reflectance, the first pit row is formed such that the first reflectance becomes substantially identical with the second reflectance.
OPTICAL INFORMATION RECORDING MEDIUM HAVING FIRST AND SECOND PIT ROW OF IDENTICAL REFLECTANCE
In a case where (i) a reflectance calculated from a reflected light amount obtained from a longest pit (P1max) or a longest space (S1max) in a first pit row is defined as a first reflectance and (ii) a reflectance calculated from a reflected light amount obtained from a longest pit (P2max) or a longest space (S2max) in the second pit row is defined as a second reflectance, the first pit row is formed such that the first reflectance becomes substantially identical with the second reflectance.
