TapeStore: A NEW TAPE STORAGE SYSTEM
TapeStore is a new kind of tape storage system which can store up to 6,000 computer tapes. No other tape storage system can hold as many computer tapes as TapeStore. The tapes look exactly like video cassettes. Many hundreds of data files can be stored on each tape, up to a maximum of 500 million bytes of data. If you stored the same amount of information on paper, you would need nearly 4.5 billion printed pages.
The machine is a tall black box with a mechanical arm. The machine is 2.5 metres high and 3.0 metres wide. This is how it works. Each tape has a code printed on it. You feed the code number into TapeStore, which then looks for the code. As soon as TapeStore locates the code, the arm reaches in and pulls out the tape.
The system is very fast. It takes the mechanical arm about 10 seconds to find the tape it is looking for. The machine then searches the tape to extract the required file, and this takes less than a minute. A human technician would have to locate and remove the tape by hand, and could take at least an hour to find the right file on the tape.
Some of the world's biggest companies, including banks, insurance companies, airlines, telephone companies, utilities and computer centres, have bought the system. They like it particularly because the system guarantees the security of their data.
TapeStore was originally developed in Canada and is now being marketed worldwide. In Europe alone, 750 have already been installed at a cost of 480,000 dollars each.

1. TapeStore is better than similar storage systems because

2. The mechanical arm finds the tape by
identifying the printed code on the tape.
3. The TapeStore system is popular with big companies because

4. According to the text, the main advantage of TapeStore over a human operator is that TapeStore
is much faster.

2. . (A, B, C)
Have you ever had to organise a conference? It is not an easy thing to do, because there is so much to think about. Before you can decide where to hold the conference, you have to ask a number of important questions. What is the purpose of the conference? How many people will attend? Where are the people coming from? Do you need presentation facilities such as videocassette players, televisions, computers, etc.? When you have answere these questions, you can decide the kind of conference centre which is best for you. There are two choices. Purpose-built conference centres will provide everything you need, although there may be other conferences going on at the same time. On the other hand, hotels are usually very comfortable, but may not have all the necessary equipment.

: Leonardo da Vinci lived (live) in Italy in the fifteenth and Sixteenth centuries.
He was a student in Florence, where he studied painting, sculpture and began a lot of paintings but he didn't finish many of them. His picture of the Mona Liza is the most famous portrait in the world. Leonardo was interested in many things. He wanted to know about everything he saw. He examined the human body. He thought that the sun didn't go round the earth. He wrote music. He designed a flying machine 400 years before the first one flew. Many people didn't understand his ideas. It is difficult to think that one man could do so much.
