WELCOME TO ISOM’07
WELCOME STATEMENTFROM THE ORGANIZINGCOMMITTEECHAIRPERSON
The 17th International Symposium
on Optical memory (ISOM’07)
will be held in Singapore
October 21-25, 2007.
It is our great pleasure to have the 17th International Symposium
on Optical Memory (ISOM) meeting in Singapore. Since thefirst ISOM(SOM) meeting was held in 1985 in Tokyo,
remarkable progresses on optical memory technologies andproducts have been made over 20 years. Total amount of opticaldrives and media shipments all over the world in 2006 wereassumed to be 230M units and 12B pieces, respectively. Opticaldrives and media are now inevitable for our daily life. Major
technologies supporting the current optical memory industry
have been presented in the past ISOM meetings. The progress ofthe optical memory industry has been strongly supported by the
progress of ISOM meetings.
Last year was the starting year of the third generation opticaldrives and media using blue laser diodes. Higher storage
capacity and data rate will provide us with completely new
surroundings for entertainment and information technologies.
Cooperated with digital broadcasting, Internet and the large
screen flat panel TV, a new digital entertainment world will becreated. Research and development for the fourth generation
optical memories have become more popular these few years.
Last year ISOM Optical Memory Roadmap was reported andindicated the milestones and breakthrough technologies for the
fourth generation optical memory. Holography, Multi-layer
recording, Near-Field recording, and other high density
recordings have been actively investigated as promising
candidates for the fourth generation optical memories. Both thirdand fourth generation optical memories and even othertechnologies will be discussed in the coming ISOM’07 meeting.
ISOM’07 meeting will be held on October 21st to 25th, 2007 at
Pan Pacific Hotel in Singapore. Welcome to ISOM’07 meetingin Singapore and the ISOM Committees hope that all of you will
enjoy the meeting.

INTRODUCTION
The 17th International Symposium on Optical Memory (ISOM)
will be held from October 21-25, 2007 at Pan Pacific Hotel in
Singapore. The purpose of the symposium is to provide a forum
for information exchange on a broad range of topics coveringscience and technology in optical memories. In 2006, ISOM
Optical Memory Roadmap final report highlighted the milestones
and breakthroughs in next generation optical data storage
research namely holographic recording, multi-layer recording,
two-photon, Super-RENS and near-field technologies. Theinterface specifications between future technologies andelemental technologies were also discussed. Participants of
ISOM’07 can look forward to the exciting developments of thesefuture technologies. Theoretical studies, conceptual ideas for highdensity optical data storage technology and discussion on future
directions in the field of optical data storage are encouraged.
The symposium venue, Pan Pacific Hotel, is centrally located in
the heart of the city overlooking the magnificent views of the city
skyline and harbour. At close proximity are the Esplanade,Orchard Road and Boat Quay. Esplanade is Singapore’s main
performing arts centre for plays and musicals. Orchard Road isSingapore premier and buzzing shopping district. Boat Quay’s
which is along Singapore River is popular for its night
entertainment. There are other sightseeing places in Singapore
such as beautiful Sentosa island, thrilling Night Safari, and iconic
Merlion Park.
