Ordered that the judgment is affirmed.
The defendant’s plea of guilty was knowingly, intelligently, and voluntarily entered. The County Court therefore properly denied his motion to withdraw the plea without a hearing, as his conclusory allegations of coercion and ineffective assistance of counsel were contradicted by the record and insufficient to warrant vacatur of the plea (see People v Curras, 1 AD3d 445 [2003]; People v Guerrero, 307 AD2d 935 [2003], lv denied 1 NY3d 572 [2003]; People v Carter, 304 AD2d 771 [2003]; People v Bedi, 303 AD2d 687 [2003]; People v Solis, 302 AD2d 542 [2003]).
There is no merit to the defendant’s contention that the court erred in failing to conduct a mental competency hearing (see People v Pitt, 264 AD2d 786 [1999]; People v Totman, 269 AD2d 617 [2000]). “A review of the plea colloquy and sentencing minutes reveals nothing suggesting that [the] defendant was disoriented or unable to understand the proceedings or work with his attorney . . . The mere existence of a notation in the presentence report that [the] defendant, some . . . years earlier, had been diagnosed as suffering from a mental disorder, does not, without more, trigger a duty to inquire further as to his competency” (People v Wheeler, 249 AD2d 774, 774-775 [1998]; see also People v Lyons, 306 AD2d 541 [2003]). In addition, contrary to his contention, the defendant received effective assistance of counsel (see People v Baldi, 54 NY2d 137 [1981]). The defendant’s attorney negotiated an advantageous plea agreement that substantially limited his exposure to imprisonment (see People v Pitt, supra at 787).
