<p>PURPOSE: To identify the format and the cartridge form of a tape. CONSTITUTION: A micro processor 230 controls a moving and speed controlling circuit 232 and a position control circuit 238 controlling a tape driving motor 234 through a normal cartridge driving roller 236. The position controller drives a screw mechanism 240, which positions a read/write head or converter 242 through a normal position arm 244. The read/write head is connected with a switching type reading filter network 248 and connected with a writing circuit 250 and a reading circuit 252. The reading and writing circuits are connected with a host computer 224 through an interface adapter 222. An optical punching sensor 258 detects physical format punches in the tape and communicates the positions of them to the microprocessor 230.</p> |
