11. . Hardware construction for TM processing system 
As is. shown. in Fig.l, 
TM data processing 
  
system consists of two TM-IDPS TH-PGS 
independant subsystems, 
i.e. TM IDPS(TM Image CPU | CPU fine 
Data Processing 
Subsystem) and TM PGS Cis)

TM IDPS has two remov 6250 8P1 
able disks(300 MBytes 
for each disk) to store 
forward and reverse scan 
data,respectively. TM Fig. 1 TM IDPS & TM PGS Hardware structure 
frame synchronizer(TMFS) 
and TM control equipment 
(TMCE) were developed 
for feeding and decommutating TM data. 
TM PGS is for feeding the TM data from CCTs and expose the 
TM image onto 240 mm film.In order to produce original latent 
film , 240 mm Laser Beam Image Recoder(LBIR) was developed.
