New York - Apple's Steve Jobs said the board has granted him medical leave to concentrate on his health.
During his leave of absence, Chief Operating Officer Tom Cook will be responsible for day to day operations, the CEO said in a statement.
Jobs will continue as CEO and be involved in major strategic decisions for the company.
Jobs did not say for how long he would be on leave but said that he hopes "to be back as soon as I can."
Jobs had stepped away from his duties in January 2009 for health reasons, although he remained involved in major strategic decisions. Cook took over day-to-day operations then too.
Jobs, a pancreatic cancer survivor, underwent a liver transplant while on leave, returning to the company in late June.
Apple is due to report its fourth quarter results after market close on Tuesday.
