A massage therapist may not be able to penetrate the deep layers of muscle and soft tissue in the first session. Depending on the situation, the therapist may need to modify the massage to keep the client comfortable so they do not subconsciously resist the work.
A CD-ROM /ËsiËËdiËËrÉm/ is a pre-pressed optical compact disc which contains data. The name is an acronym which stands for  Compact Disc Read-Only Memory . Computers can read CD-ROMs, but cannot write to CD-ROMs which are not writable or erasable.
CD-R (for Compact Disk, recordable) is a type of write once, read many (WORM) CD format that allows one-time recording on a disk. The CD-R (as well as the CD-RW) format was introduced by Philips and Sony in their 1988 specification document, the Orange Book. Multisession CD is a recordable CD (like a CD-R) that allows data to be recorded to a disc in more than one recording session. If there is free space left on the CD after the first session, additional data can be written to it at a later date.
