I just got this exact same question for homework in my CS course today, what a surprise. A floppy disk, magnetic coated and rotates.
Yes both are secondary storage devices. Primary storage devices include RAM & ROM. Secondary storage devices include magnetic disks like hard disks and cds(optical disks)
That's a hard disk.
Hard Disk Drive, Floppy Drive
A magnetic tape is a secondary storage media used to access data in a sequential way
The overall trend in secondary storage device is the migration from rotating magnetic discs to solid state storage. Solid state drives (SSD's) are however considerably more costly than older types of storage.
it is the hard disk
A hard disk drive consists of one or more thin disks that spin at high speed (1200 to 15000 rpm) while magnetic heads read data from them, hovering extremely close to them without making contact.

track mean a path in secondary storage, storage contains traks in circles and in every track there is sectors means tracks are dividing in different chunks of sectors
Hard disk drives are a highly popular medium of computer storage because of their enormous capacity compared to other media. As a disadvantage, they are more costly and, depending on the type, have a limited lifetime.
