Parkin, an IBM researcher, is looking into a new idea in an IBM lab. If it proves successful, electronic devices can hold 10 to 100 times the data in the same amount of space. That means the iPod that today can hold up to 200 hours of video can store every single TV program broadcast (播放) during a week on 120 channels. Parkin thinks he is close to a breakthrough. This can increase the amount of data stored on a chip.At present the flash drives (闪存卡) business is growing quickly. They are used in digital cameras, cell phones and PCs. Flash drives with multiple (多个) memory chips store up to 64 gigabytes (十亿字节) of data. A single chip is expected to reach about 50 gigabytes in the next five years.However, flash memory has a problem. Although it can read data quickly, it is very slow at storing it. That has led the industry on a hunt for new storage technologies.Scientists say Parkins new computer memory, called “racetrack memory (赛道内存）”, could begin to replace flash memory in three to five years.36 . 补全句子。If _, electronic devices can hold 10 to 100 times the
