Writing to a CD-R 1. A single track runs in a spiral pattern from the center of the disc to the side. 2. A high powered laser is shone onto the CD-R, changing the transparency (permanently) of the dye above. The transparent and opaque parts represent binary 1s and Os. 3. The disc spins and the laser follow the track, putting the binary data onto the CD-R in a spiral track. 4. The data has been written. Reading from a CD-R 1. A single track runs in a spiral pattern from the center of the disc to the outside, this track is made of pits and lands to represent the ones and zeroes of binary data. 2. A low-powered laser is shone on the surface and the reflection is captured in a photodiode sensor. The opaque dye will reflect differently to the transparent dye (which would just reflect the metal underneath it), meaning it can tell the difference between a 1 and 0. 3. The disc spins and the laser follow the track. 4. The binary data (the 1's and Oss) are put together and the CD-R has been read. On the same knowledge answer A magnetic-tape system accommodates 2400 ft reels of standard nine-track tape. The tape is moved post the recording head at rate of 200 in/sec. (a) What must the linear tape-recording density be in order to achieve data transfer rate of 10 Mbits/sec. (b) Suppose that the data on the tape is organized into blocks each containing 32 kbytes. A gap of 0.3 in separates each block. How many bytes may be stored on the tape?

Writing to a CD-R
1. A single track runs in a spiral pattern from the center of the disc to the side.
2. A high powered laser is shone onto the CD-R, changing the transparency (permanently) of the dye
above. The transparent and opaque parts represent binary 1s and Os.
3. The disc spins and the laser follow the track, putting the binary data onto the CD-R in a spiral track.
4. The data has been written.
