Ingolf's Professional Career
        
1974 University Hamburg / Germany;   PhD in Plasma Physics
Thesis:  "Spatial and temporal spectroscopy of a streamer discharge in nitrogen"

 
 

 Block Diagram of Measurement Apparatus

 

Spatial Temporal Development of Electron Density

 

   

  As part of my teaching responsibilities I gave seminars about PDP 8 minicomputers, and set up an internal network for process control of scientific experiments.
     

   
1974 - 1984 Philips Research Lab in Hamburg;   Scientist / Project Leader
Research topics: "Optical Recording"
     

 
I participated in the research of:
Write Once Optical Recording
  (AMOR: audio multichannel optical recorder for CD editing)
Holographic Memory
Erasable Optical Recording in iron garnets
Erasable Optical Recording in amorphous
  Magneto Optic (MO) Materials

I became project leader for "Small Form Factor Magneto Optic Drives"
 

 

Laboratory model of an erasable magneto-optic storage device with a capacity of 10 MByte corresponding to 10 million characters. The conventional "floppy disk" in the background has only 1/10 of the capacity.
  Philips Research Lab Hamburg 1982:
 
"Magneto-optical (MO) phenomena can be used with advantage in information storage. Disks of 5 cm diameter can store 10 M Bytes, which is equivalent to about 5,000 pages of DIN-A4 size. They are smaller, less sensitive to damage and cheaper than floppy disks.
 Since, in addition, the new disks store ten times more data, they lend themselves quite naturally to the "floppy of the future".
All these possibilities are going to revolutionize the design of the "office-of-the-future". It will be easy to generate documents composed of text and graphics, and to transmit, receive, edit, input, store and output such documents."

 
     

   
1984 - 1988 Verbatim / Kodak in Sunnyvale / California;   VP Drive Development
3.5" media / drive development
     
   

Under the direction of Jeff Bates - one of the gurus of magnetic recording - I started a small group to develop a magneto optic drive as the "Floppy of the Future".  In the beginning we did not even have a screw driver but after one year we had developed our own mastering machine, sputtering equipment for magneto optic layers, test equipment, and fully functional drives. 

 

The drive was shown at the NCC  (National Computer Conference) 1985 in Chicago.  It was the "hit of the show":

CHICAGO — For Ingolf Sander of Verbatim Corp., the third time just might be the charm —for him and the personal-computer industry.
Before coming to California from West Germany two years ago Sander twice developed record-player like devices called optical disks that use laser beams to store or retrieve vast quantities of information.  Optical disks store hundreds of thousands of times more information than the current generation of Magnetic disks. They are the wave of the future in data storage for personal computers.

 
      

   
1988 - 1995 LaserByte;   Founder, President, VP of Engineering
3.5" MO Drive, Development, Production
     
   

I formed a joint venture with Hyundai Electronics to develop MO drives and start pilot production.  As the picture (by my daughter Tina) shows  LaserByte was a busy place with R/D activities in optics, electronics, mechanics (and some fun).
 

 
     
   

We successfully developed the fastest drive in the industry with 230 MB capacity, and manufactured 2000 drives.  
Ultimately the CDR (rewriteable CD) based on phase change technology became a big commercial success - a small optical drive in every computer. 

 
Having explored the limits of magneto optic recording I went back to more basic research in optical recording.

     

   
1995 - 1998 Optitek;   VP Drive Development
Holographic Memory Research / Development
     

  Holographic recording is an attempt to increase the storage capacity by storing the information in the volume - not in a single layer.  Optitek was part of a precompetitive consortium with the members:  IBM, Stanford University , Kodak, Rockwell, and GTE to develop the technology.  Due to the lack of suitable recording materials viable commercial products could not be developed.   
     

   
1998 - 2001 C3D;   VP System Development
Multi Layer Fluorescent Disc Research / Development
     

   

Another approach is storage in many layers.  C3D found a unique way for storing data in up to 20 layers using fluorescent materials - however stability problems in the material could not be overcome.

C3D' s headquarter was in New York, research labs were in Moscow, Tel Aviv, and in Lviv / Ukraine.  I had opportunities to work in all these places, meet diverse people, and visit famous attractions.
