.*NB"1541SPEED.DOC".1541SPEED-HEAD.DOC.. A MINOR SPEED IMPROVEMENT IS POSSIBLE ON THE 1541 THROUGH SOFTWARE ADJUSTMENT OF THE HARDWARE AND SOFTWARE TIMERS THAT R EGULATE ITS HEAD MOTION AND THAT MEASURE OUT THE PAUSE DURING WHICH A DISK COMES UP TO SPEED. I'VE FOUND THAT HEAD MOTI ON CAN BE SPEEDED UP ABOUT THREE TIMES, AND THE SPIN-UP PAUSE CUT TO ABOUT ONE H ALF, OF NORMAL...THAT CAN SPEED UP PROGR AMS THAT USE TWO FILES ON THE SAME DISK, DURING WHICH THE HEAD MAY SHUTTLE BACK AND FORTH A LOT, HANDLING A DISK BLOCK F IRST FOR ONE FILE, THEN FOR THE OTHER. IT CAN SPEED UP OPERATIONS THAT INVOLVE SEVERAL LITTLE BATCHES OF DATA, FOR WHIC H THE DISK MAY FREQUENTLY STOP AND RESTA RT. IT CAN REDUCE THE TIME SPENT VALIDA TING A LONG DIRECTORY...THE QUICKER HEAD MOTION EMPHASIZED A PROBLEM WITH MY DRI VE, AND I'M NOT SURE I'VE FOUND A LASTIN G SOLUTION: THE SLIDES THAT GUIDE THE H EAD BECAME A LITTLE BIT GUMMY AFTER A YE AR OR SO OF USE. THE HEAD STEPPING BECA ME QUITE LOUD AND RAGGED SOUNDING, APPAR ENTLY BECAUSE THE HEAD SLIDE WOULD BIND A LITTLE AND THEN HOP LOOSE. GREASING T HEM LIGHTLY WITH A GOOD PHONO LUBE MADE THE DRIVE QUIET AS A MOUSE AGAIN, BUT AG ED GREASE CAN BECOME A GUMMY MESS IN ITS OWN RIGHT. I USED A PRODUCT CALLED LUB RIPLATE. DOES ANYONE KNOW HOW WELL THAT STUFF AGES AND IF THERE IS A BETTER PRO DUCT TO USE FOR THIS? I'M NOT A FREQUEN T Q-LINK USER, SO ANY SUGGESTIONS COULD BEST REACH ME THROUGH COMMENTS ABOUT THI S FILE. .DNA MAY 1987.
