Calluna's managing director, Norman White, was a director of Rodime, an ill-fated high technology company quoted on the full list. Rodime, which designed and made hard disks for personal computers, lost its way in 1991 after an ambitious expansion programme in the US and the Far East.
Started in 1980, Rodime reached a turnover of more than pounds 80m by 1985. Although it is still listed on the market it no longer trades, deriving its income from licensing patents.
Dr White denied that Rodime had been a failure, saying it traded successfully throughout the Eighties. He set up Calluna with five former Rodime colleagues in 1991.
Calluna designs and manufactures a credit card-sized 80- megabite hard disk which fits into specially created slots in laptop and notebook computers. Because the card is transferable between computers users do not need to take their PCs, electrical flex or batteries with them.
Calluna, turnover pounds 3m, has yet to make a profit. Donald MacDonald, finance director, said it was 'doubling turnover every two months'. He anticipates industry sales of the card growing to more than three million by 1997.
The company will apply to join the full list in 1996, when the USM closes, by when it will have the required three-year trading record.Reuse content
