Bolt thinks winning Olympic gold would be a greater achievement
Usain Bolt set a new 100m world record by clocking 9.72 seconds at the Reebok Grand Prix meeting in New York.
The 21-year-old Jamaican, who won silver in the 200m at last year's World Championships, was running the 100m for just the fifth time.
Bolt beats the previous best of 9.74 set by compatriot Asafa Powell.
"I wasn't looking for a world record but it was there for the taking so I just went out there and ran my best race," he said.
Bolt beat Tyson Gay into second place, with the American running a personal best of 9.85.
The 6ft 5in Bolt made the track world sit up and take notice on 3 May when he clocked the second-fastest 100m time in history, 9.76 seconds.
Bolt has made no secret of the fact that he sees himself as a 200m specialist and earlier in the week he was still undecided if he would even enter the 100m Jamaican Olympic trials.
100m RECORD EVOLUTION
9.72 U Bolt, New York 2008
9.74 A Powell, Rieti 2007
9.77 A Powell, Athens 2005
9.79 M Greene, Athens 1999
9.84 D Bailey, Atlanta 1996
9.85 L Burrell, Lausanne 1994
9.86 C Lewis, Tokyo 1991
9.90 L Burrell, New York 1991
9.92 C Lewis, Seoul 1988
9.93 C Smith, Colorado 1983
9.95 J Hines, Mexico 1968
However, after becoming the fastest man on the planet he confirmed he would now double up in Beijing: "I'm definitely going to run the 100 in the Olympics.
"I've just got to concentrate now and work on my 200 some more, because I haven't been doing a lot of 200 work."
And despite setting the world record, Bolt still considers the Olympics to be the big prize.
"I don't think there's any comparison between the two," he said. "You've got to be Olympic champion or world champion to really count.
"Tomorrow if someone comes and runs faster than me I'm no longer the fastest man in the world. If you're the Olympic champion then they have to wait four more years to get you again.
"I think the Olympics is the biggest thing, so I'm looking for that, definitely."
Bolt has primarily used the shorter distance to improve his start and admitted he was happy there had been a false start the first time he went into the blocks.

I'm telling you, Michael Johnson's 19.32 in the 200m must be vulnerable because Mr Bolt is coming for that one too

"I was glad of that first false start," he said. "My first start wasn't that good but I knew if I got Tyson on the start I would have a better chance of winning.
"Tyson and I aren't really good at starting so, my coach said concentrate on your drive (out of the blocks) and transition phase, get it right and just take it from there and I did exactly that."
He added: "I got out well. I've been working on my start for a while. I think I did good work today on my start. I'm just happy with myself."
Triple Olympic champion sprinter Usain Bolt has pulled out of a race this weekend after suffering minor injuries in a car accident in Jamaica.
Bolt crashed his BMW into a ditch and was taken to hospital where he had thorns removed from his foot, having stepped on them getting out of the car.
And he will not now race in Saturday's Jamaica International Invitational.
The 22-year-old won gold in the men's 100m and 200m at Beijing in record times and was also a relay winner.
"We will continue to monitor his progress over the next few days," said Bolt's agent Ricky Simms.
"It's too early to say if this will have any impact on his training and racing programme in the next few weeks."
Bolt is set to run a 150m street race in Manchester on 17 May.

Olympic sprint champion Usain Bolt will take part in the 150m street race in Manchester on Sunday, 17 May.
Bolt's participation was in doubt after he was involved in a car crash in Jamaica on 29 April and had to have thorns removed from his left foot.
The 22-year-old, who won gold in the 100m, 200m and 4x100m relay at the Beijing Games last summer, returned to light training last Friday.
Bolt's coach Glen Mills said: "He looks OK and will be fine for Manchester."
The 150m race will see the Jamaican competing against top British sprinters Marlon Devonish and Simeon Williamson in Manchester city centre.
Bolt, a keen Manchester United fan, is looking forward to meeting the team at their training ground and has promised to give Cristiano Ronaldo some sprinting tips in return for a signed shirt.
He is also due to be presented on the Old Trafford pitch during the half-time interval at Saturday's match against Arsenal.
Bolt will also attend the Manchester United Players Awards on Sunday where he will present the fans' player of the year prize.

Usain Bolt is certain he will emerge victorious from the 150m street race in Manchester on Sunday evening.
The 22-year-old Jamaican won gold in the 100m, 200m and 4x100m relay at the Beijing Olympics last August.
He has taken time to recover from a recent car crash but will face Brits Marlon Devonish and Simeon Williamson.
Asked if he would win, he said: "Definitely. It's always business and if you're lined up alongside me I take you seriously."
Bolt has a bye into the final, his opponents in the race having all agreed to this with the race organisers.
The world 100m and 200m record holder hopes he can break Donovan Bailey's fastest-ever 150m time of 14.99 seconds over the rarely-run distance.
"I think I ran 14-something but I have run it only in training. I don't go worrying about times. That is when you start running slower," said Bolt.
The sprint is one of several events running on the day of the 10km Great Manchester Run, a mass-participation event featuring 33,000 runners. Ethiopian great Haile Gebrselassie is the star of the men's elite race, while Andrew Lemoncello, who has been in impressive form of late, leads the British challenge.
In the women's event, Kenyan Vivian Cheruiyot is being tipped to challenge Paula Radcliffe's British all-comers' 10km road record of 30 minutes 38 seconds.
Olympic 400m gold medallist Christine Ohuruogu takes on Beijing 100m and 200m finalist Debbie Fergusson-McKenzie of the Bahamas in the women's 150m race, being run on a world-standard track in the city centre.
