Los Angeles: The doctor sentenced to four years in prison for causing Michael Jackson's death has filed a notice that he intends to appeal the conviction.

Conrad Murray signed the notice that was filed in Los Angeles late Friday seeking all records and transcripts from the case. The filing does not indicate the basis on which Murray will argue to overturn his conviction or sentence.

Murray was sentenced on Tuesday for his involuntary manslaughter conviction, but the term will be automatically cut in half.

Superior Court Judge Michael Pastor criticised Musrray's conduct, calling him a disgrace to the medical profession.

Murray's challenge would be heard by a state appeals court in Los Angeles.
