WELCOME TO ISOM2003
WELCOME STATEMENTFROM THE ORGANIZINGCOMMITTEECHAIRPERSON
The 13th International Symposium
on Optical Memory (ISOM2003)
will be held in Nara, Japan
November 3-7, 2003
Two years ago an economic bubble in IT business sector collapsed
and during the first half of this year the world economy has been
influenced a great deal by an epidemic of SARS. The world
economy is still suffering from the bust of the bubble economy andan epidemic of SARS.

Although the world economy has been in abad situation for a few years, Internet and the related business havebeen developing constantly. The number of Internet users in theworld has exceeded over 5 hundred millions in 2001 and by
year-end 2005 the number will double to 1.12 billions. On aparallel with the increase of users, broadbandization of Internet isalso continuing in the world. According to the development ofInternet and the related business users are storing a lot of digital
data personally. This leads to the increase of demand for the opticalstorages with the higher performance and the larger capacity. The
number of the DVD players that were sold in the world in 2002 wasestimated to reach more than a hundred million although that in2000 was approximately 27 million. The number of the DVD
recorders sold in the world in 2002 was 1.3 million and that in 2005
is estimated to get to 22.6 million. When the recovery of economic
situation is achieved much more optical storages with higher
performance and the larger capacity will be required for diversified
purpose.
In order to respond the requirement development of newtechnologies for future optical storages is fundamental.

In

ISOM2003 the new technologies that will be essential for the future
optical storages will be discussed.
ISOM2003 will be held on November 3-7, 2003 at the Nara-ken
New Public Hall (Shin-Kokaido) in Nara, the oldest city in Japan.

4Nara is very famous worldwide for cultural treasures, old temples
and beautiful scenery. The Shin-Kokaido is originally a theater for
Noh, Japanese lyrical drama. The presenters will get the privilege
to be able to present on the stage of Noh.
Welcome to ISOM2003 in Nara and the ISOM Committees believethat all of you will enjoy the great event of ISOM2003, the oldest
city in Japan and the cultural treasures in Japan.

ISOM2003

INTRODUCTION
The 13th International Symposium on Optical Memory (ISOM)
will be held from Nov. 3rd to 7th 2003 at Nara-ken New PublicHall (Shin-Kokaido) in Nara Prefecture, Japan. The purpose of thesymposium is to provide a forum for information exchange on
broad range of topics covering science and technology in opticalmemories. This year, 2003, high-end DVD systems using blue laser
were shipped to the market. In addition, as discussed in
ISOM/ODS2002, several novel approaches such as holographic,
multi-level, three-dimensional, near-field and super-resolution
technologies will be the main focuses on ISOM2003 for the next
generation optical storage. The pure and applied theoretical studies
in physics and mathematics will play a great role in further
supporting and developing these new technologies. We welcome
such novel proposals and basic concepts available to future storage
technologies.
The

symposium

is

held

at

Nara-ken

New

PublicHall(Shin-Kokaido) closely located at our world treasure, 'Todaiji
temple,' which was built in the 8th century and one of the oldest
and biggest wood-made temples. In there, the biggest Buddhist has
been enshrined. The city, Nara, had been the ancient capital ofJapan by the 8th century.

SCOPE OF THE SYMPOSIUM
ISOM 2003 will discuss the current status of optical memory
system design and applications, together with new developments inthe areas of media, lasers, basic theory, system sub-components,
and a range of future technologies. In addition to ordinary
contributed papers, invited papers on important topics will bepresented.

Topics to be covered in this symposium include, but

are not restricted to:
1. Basic Theory• Diffraction, Polarization• Analysis of Mark Formation• Magneto-Optical Effects6• Near-Field Optics, FDTD Analysis
