About floppy disks About floppy disks On the QY700, floppy disks are used to save data that you create, or to exchange data with other devices. This section explains the types of floppy disks that the QY700 can use, and things you should know about floppy disk handling. Types of floppy disk • The QY700 can use two types of floppy disk: 3.5 inch 2HD and 3.5 inch 2DD. • Before data files can be stored on a floppy disk, the disk must be formatted (initialized). (→ p.316) • The QY700 formats 2HD disks to 1.44 MB (megabytes) and 2DD disks to 720 KB (kilobytes) MS-DOS format. (MSDOS is a registered trademark of Microsoft Corporation.) Since this format is common to computers as well as to Yamaha products and the products of other manufacturers, it allows disk compatibility. 3.5 inch 2HD 1.44 MB 3.5 inch 2DD 720 KB Inserting a floppy disk • With the label side of the floppy disk facing upward, insert it into the floppy disk drive starting with the end with the shutter. • Push the disk gently in until it clicks into place. Push disk gently in until it clicks into place Removing a floppy disk • After making sure that the floppy disk drive is not in use, firmly press the eject button, make sure that the floppy disk has been completely ejected, and remove it from the drive. Press the eject button firmly and accurately, and make sure that the disk is ejected • If the disk catches inside and does not slide out smoothly, firmly press the eject button once again, or re-insert the floppy disk and then press the eject button once again. • While the disk-in-use indicator is lit, data is being transferred between the floppy disk and the QY700. While the disk-in-use indicator is lit, never turn off the power or attempt to remove the floppy disk. Doing so could damage not only the floppy disk but also the floppy disk drive. Regular cleaning of the disk drive heads • Floppy disk drives contain a high-precision magnetic head. When a floppy disk drive is used for an extended period, the heads will become soiled by magnetic particles from the floppy disk. This will increase the chance of errors occurring when data is read or written. • In order to keep the floppy disk drive in good condition, we recommend that you clean the heads regularly (once a month). Floppy disk handling and storage • Floppy disks should not be placed in locations of direct sunlight or temperature extremes, or in excessively damp or dusty locations. • Do not allow floppy disks to come near objects that have a strong magnetic field, such as televisions or speakers. • Before turning off the power, remove the floppy disk from the disk drive. Leaving a floppy disk in the drive for a long period with the power turned off can cause the disk to become dirty, producing read/write errors. 302 Chapter 7. DISK MODE
